Take your entire library on the road

0


By Greg Illes

By now, most folks know about e-books (electronic books), those microscopic packets of electrons that blossom magically into entire books in full color. E-books are sometimes embraced, sometimes hated, and nearly universally misunderstood to some extent.

For RV life, electronic books are a huge blessing, virtually eliminating any space or weight taken up by conventional tomes. So it’s worth looking at some features and details, and getting a full understanding of the virtues of this technology.

• E-books are cheaper — On Amazon, a typical e-book may sell for $5-$10, whereas a paperback, and especially a hardcover, will be more costly.

• E-books don’t require a special reader — You don’t need another piece of electronicsbecause you can read an e-book on a computer, a smart phone, a tablet or a laptop.

• E-books can be easily shared — If you share an Amazon account, you can download the same e-book to all of your shared devices. The same book can be read simultaneously on two or more devices. (However, you might not get it to open exactly where you left off.) Non-copyrighted e-books can be copied and shared by email or thumb-drive.

• There are thousands of free e-books — On Amazon, Gutenberg, and hundreds of other sites, there are far more choices of really good books than you could absorb in a lifetime, all free for the download.

• It’s super easy to share a book — If you have a free book, you can email it to a friend; if it’s a pay-for book, you can send them the link to purchase it (or send them a gift by email). It’s no longer necessary to hand over a two-pound printed copy for a friend to share your reading experience.

• E-books don’t need a reading light — No lamp required. Want to read in the dark? Not a problem. Poor light in a waiting room, or wishing not to disturb your sleeping partner, don’t impact your ability to keep on reading.

It’s pretty easy to see how the benefits of e-books fit nicely into the RV life. And so far we’ve only talked about printed-matter books. There are also extensive choices for audio books, which also take no more than a bit of disk or USB thumb-drive space. Imagine being able to “read” a new book as easily as listening to the radio while you’re driving down the road.

True, some folks just love the feel of flipping the pages of a paper book, and this merit can’t be argued. But you do get quickly accustomed to the convenience and flexibility of the electronic style, and most of us can give up a little nostalgia for the sake of carrying our entire reading library along on every trip — in our pocket or purse.

Got a smelly Dometic toilet? This could be the problem

By Steve Savage, Mobility RV Service

If by chance your new RV came with a Dometic Series 300 commode as standard equipment and suddenly your bathroom smells like a cesspool, here’s what might have happened. Unlike commodes in the past, the top and bottom halves of this appliance are sealed internally and are not to be separated. Do not attempt to separate them!

All goes well unless the seal breaks, and the rear of the commode becomes a storage container for bodily waste. When this happens the entire commode must be replaced. The Series 300 has been replaced by Series 310 at your service center.

If you choose to replace it yourself, shut off the water to your RV. Disconnect the water line at the rear of the commode. Unbolt the commode from the floor and lift it straight up. Do not tip it or turn it upside down or you will have an incredible mess. There are no parts from the old commode that will be reused on the replacement.

Editor’s note: Several RVers have commented about this problem; all have reported that Dometic was quick to respond by sending out a new 310 model toilet.

Missing or damaged roof vent? “Spacey” suggestion to the rescue!

0

By Russ and Tiña De Maris

We recently told you about a video on using reflective emergency blankets. Reader Astrid Bierworth was quick to let us in on yet another use for these easy-to-store “space” blankets.

“While in Utah recently, we were hit by a sudden, damaging hailstorm. Several RVs in the park where we were sustained damage. The hail was not large, but the wind drove it almost like bullets. Several units lost their vent lids. Those of us with vent covers (like MaxxAir) were OK, but those whose vent lids were somewhat brittle from sun exposure suddenly had a problem keeping rain out of their RVs.

“Sheets of plastic became a hot commodity. I happened to have some which I gave to a neighbor, but who carries sheets of plastic around in case the vent lid gets damaged or there is some other form of water intrusion in the RV? Still, most of us carry duct tape.

“This is where I think these reflective emergency blankets could come in handy. They are very light and small, and so much easier to carry around than a sheet of plastic. They would make great temporary rain-keeper-outers!”

Astrid’s suggestion surely could have helped us some years back. Tooling down a windswept freeway outside of Portland, Oregon, we found (on a stop) that one of our roof vents had just completely “taken a powder” (left). We lost a couple of hours locating a window glass company, who cut us the properly sized chunk of clear acrylic to temporarily “plug the hole.” A well-placed, well-taped reflective blanket could have probably handled our problem with a lot less time loss — and would have been much cheaper, to boot!

You can find a wide variety of these clever blankets on Amazon.

Pick your next generator carefully

By Greg Illes

Before you repair or rebuild that Onan built-in generator, and certainly before you purchase another portable generator, there are some relatively new issues to be aware of and consider.

generator-736The old Onan 4KW series, and most older portable generators, use a fuel motor (gas/diesel/propane) to drive a motor-generator. This requires that the engine run at a constant 3,600 rpm in order to achieve the standard 60Hz AC voltage frequency (sine wave). The end result of this technology is a lot of weight and noise.

A typical open-frame portable (think contractors, Home Depot, Harbor Freight, etc.) will make enough noise to compete with jet takeoffs at your local international airport. Say goodbye to a peaceful campground if one of these turkeys is within a hundred yards of your campsite.

The standard of the industry, the Onan 4,000 kilowatt series, is much quieter, but still pretty audible across several campsites. But it’s also HEAVY, almost 200 pounds in a typical installation. People love their Onans because they’re built in, draw fuel from the RV tank, have a remote start and are (mostly) trouble-free. Certainly, if your RV has one already and it’s working okay, you’re not likely looking to replace it. But I’ve run into more than a few RV owners who have bought quieter, more fuel-efficient units to run in addition to their Onans.

For any major change in generator resource, new or replacement, the newest technology to be aware of is the inverter-generator. These products have created a sea change in the market, and I’m kinda surprised that Onan has not come up with a competitive offering. (Are we looking at a replay of the U.S. auto market with Japan?)

The inverter-generator also uses a fuel engine, and many are very quiet in operation. But more importantly, the engine drives a very different kind of electrical generator. This design drives a variable-frequency motor generator which powers a full-electronic inverter power supply. The electronic supply puts out 60Hz regardless of engine speed. Without going into a lot of technical detail, let me just say that the final result is that the engine only has to turn fast enough to power the existing load.

How does this work? If all you’re doing is running your lights and the TV, the inverter-generator runs just above idle, barely audible inside the RV. Fire up the AC or the microwave, and the generator leaps to life, powering up into the typical high-rpm growl (although still MUCH quieter than the open-frame models). When the microwave shuts off, the inverter-generator settles back down to a purr again.

Using one of these in a campground environment is a dream come true. At low load, these little units can’t be heard over a light breeze even in the next campsite. They barely sip gasoline, running many hours on one gallon. There are also remote-start units available, and power ratings from one to four KW and more. The 2KW units weigh about 50 pounds — that’s it.

The next time you see a fellow camper walking around his campsite and it sounds like he’s pumping up an air mattress, go check out his generator. He’s likely peacefully powering his rig with a red (Honda) or blue (Yamaha) inverter-generator, and you can thank him for his campground courtesy.

Editor: Browse through the large selection of inverter-generators available at Amazon.

Keep some essentials — and more — in your toad


By Greg Illes

Statistics tell us that 80 percent of the motorhome population tows a car behind their rig. Add to this the number of people pulling trailers and fifth wheels and you have a whole bunch of folks who use “local transportation” when they’re camped.

A lot of the time, the “ground vehicle” is just used for going to the store, visiting local sights and similar short trips. But if your travel is just a little more adventurous, you could find yourself quite a ways from RV-home, with all those home comforts and tools far out of reach.

If you are (as we are) four-wheeling capable, then the radius of day operations gets truly remote. Because of this, we’ve developed a toad-kit of day-travel accessories. We have been well over 100 miles from our RV on day trips, occasionally most of it on dirt roads, so our kit is pretty extensive. The following is actually only a partial listing.

Handy Stuff — Jackets, hats, hiking staffs, day-packs, drinking water, snacks, cameras, spare batteries, cell phone chargers. Basic first aid kit in the day-packs. Rags, ropes, flashlights, duct tape.

Survival Gear — Small tent, space blankets, rain ponchos, satellite link (InReach is our current choice), more snacks.

Recovery Gear — Tool kit, tire patch kit, air pump, winch cable extension, winch hardware, snatch strap, shovel, pickax, saw, spare gas, spare water, spare drive belt, jumper cables. A really good jack (hi-lift).

As you can see, we hate getting stuck or seriously inconvenienced. We are prepared for enjoying our excursions in comfort. We are also prepared for the occasional mishap, bad weather or even a serious breakdown without being badly compromised in comfort or safety.

You may or may not want to stock up as aggressively — but consider how your day might go if you are ten miles up a lonely dirt road when a radiator hose blows. Long, hard walk and it’s getting dark. No cell phone coverage. Hmmm … Maybe some good duct tape, spare water and a flashlight would be nice to have?

Cold weather RVing no-nos

0

By Steve Savage, Mobility RV Service

With winter now upon us, it is time to toss out a couple of things that are not good ideas, if you’re using your RV this winter.

Most folks try to save money on propane by using electric space heaters in their campers. Electric heaters also give some respite from those noisy furnace blowers. Yes, I know, furnaces are propane pigs, often going through something in the area of a gallon of propane per three hours of run time, and you sure don’t need to tell me how noisy they are. It’s like sitting next to a miniature jet engine in many RVs.

So what’s the problem with electric cube heaters or something similar? Two things: First, many campers, even those four-season models (a misnomer if there ever was one!), are designed with ducting that heats water lines and dump tanks. With no furnace heat, water lines can freeze and dump valves can ice up. In a worst-case scenario, in one instance I had to replumb water lines when the furnace quit and the owner switched to electric heaters for several days. If you are going this route, try to use the furnace some to help keep things from freezing and open cabinet doors to allow heat to reach water lines.

Second, to revisit a point I covered in an earlier post, placing high draw loads on wiring can be a sure-fire way to melt things. I spent part of today installing an inverter to replace one that had burned out a couple of days ago. The owners, like so many of us, did not give thought to what might happen if the inverter had to transfer power to a large microwave, an electric space heater and a coffee maker all at one time. No, the breaker did not trip. Breakers have only one job and that is to keep wiring from starting on fire. They do not protect anything that is on the line that is getting hot.

In this case, a very large diesel motorhome had every shore power item in the RV except the air conditioners and the washer/dryer running through the inverter. The load was large and long, meaning the transfer switch in the inverter got very hot. So hot, in fact, the inverter reeked of burned circuit boards when I removed it and installed a new one.

Now, if you are thinking, “Why on earth would a manufacturer route every receptacle in the coach through the inverter,” the answer is simple: The engineer who designed it was attempting to make sure there was power everywhere, all of the time, but gave no thought to what might be plugged into those receptacles and drawing power at the same time.

One final point: The term “four-season” has no real meaning when it comes to RVs, and can mean anything from tank heaters to more insulation and all points in between. If you ask a manufacturer what it means with their models, the answers you will get are likely to be all over the map and generally means the RV is suitable for use until temperatures reach about freezing. How much lower you can safely go after that varies widely, with very few rigs suitable for below-zero temperatures.

My wife and I winter camp and have done so in cold and even below-zero weather at times, but doing so requires you understand the construction of your RV and make adjustments accordingly — or, as one RV owner said to me one time, “Sure, I winter camp — just not where it’s cold!”

Shake, rattle, roll down the road — but the crystal stays put

0

By Jim Twamley

It’s often been said that by driving or pulling our rigs down the road we expose them to earthquake-like conditions. It’s a wonder more stuff doesn’t fall and break! So, how do we secure something like a crystal vase that we want to stay in one place while we travel? The answer is found in products like Museum Gel, Museum Putty and Museum Wax.

Each of these stick-’em products has a specific recommended application. We added color treatment to Museum Putty to show where it’s attached to an object we don’t want to shake loose. Here an RV dealer uses Museum Putty to hold the dishes secure on the table so they can take customers on test drives without breaking the decorations.

Museum Putty will secure most anything to keep it from falling and breaking. Museum Putty comes ready to use in a sheet. You just pull off a chunk and roll it in your fingers until soft, then stick it on the bottom of the item you are securing. Then you slightly twist the item with the putty onto the surface and “presto,” you’re done. It will not harm wood finishes and it can be used over and over again. You can purchase Museum Putty at Amazon.

Museum Gel (also available at Amazon) is another product that works best for anchoring crystal and glass objects because it is clear. You apply it the same as Museum Putty, but it takes about an hour to set. Museum Wax (at Amazon) is the best choice for more permanent placement of objects. It works well on wood shelves but can become more difficult to remove if objects are left in place more than one year.

Can I run my 30-amp RV on a 20-amp outlet?

By Russ and Tiña De Maris

For some new to RVing, electricity is a mysterious force — one difficult to sort out. Here’s an example: “My RV has a 30-amp connector. I want to plug it in at home but I only have a typical outlet — 20 amps, I think. Will it hurt to plug my RV in and use it? And how can I do it?”

The answer isn’t a straight “yes” or “no,” because so much depends on what electrical-consuming appliances you’ll want to use in your RV. Plugging an RV into a “smaller” circuit simply requires the appropriate adapter. You’ll find these at any RV parts outlet, at many Walmart stores, and at Amazon. Not only does this apply to a “30-amp-loving RV,” but to 50-amp-wired RVs as well.

What happens when you plug that “bigger” drawing plug into a “smaller” circuit simply means you have less available power. You’ll probably be able to use most (if not all) of your appliances and other power consumers, but you won’t be able to use them all at once.

The big power consumers — air conditioners and water heaters with electric option, for example — will have to learn how to share — run one biggy, shut it off, turn on another. Most other stuff, like lighting, fans and water pump, will all probably be happy to coexist and operate at the same time. You’ll know if this isn’t the case when the breaker serving the power outlet you’re plugged into trips and plunges you into the outer darkness.

But a BIG word of caution: Never try to “extend your reach” when using a setup like this with the addition of an extension cord to your rig — it adds one more layer of “resistance” to the mix and could get you in trouble. It’s also wise to have an inexpensive line voltage meter plugged in and monitoring. For less than $20 you can buy one that plugs into one of your RV’s power outlets, and a quick glance will tell you how much voltage is reaching your rig. If it drops below 110 volts, it’s time to turn a few things off, as low voltage can readily kill some items — like air conditioner motors. Amazon has a selection of voltage meters.

What about “adapting up,” the other way? Say you have a 30-amp plug on your RV and the only available power outlet is a 50 amper? In this case, you’ll have plenty of power available for your needs — you’ll simply need the appropriate adapter. There’s no need to worry that you could have “too much power.”

Tips for the snowbirding boondocker

0

By Bob Difley

Snowbird season is on us. If you are planning to spend a few months boondocking in the deserts, you may find the following tips helpful as well as a partial check list before you set out, or to make adjustments if you’re already doin’.

• Consider installing solar panels. Most of the desert is wide open to the sky and you get a full day’s worth of charging — even though the days are shorter. Even a single panel will provide enough electricity to run some of your systems, decreasing the amount of generator run time.

• Also consider a catalytic heater, which runs on propane — and since it has no fan, it draws no electricity. Your built-in forced air heater will quickly drain your batteries on those crispy desert nights.

• Make up a desert day pack for hiking, biking or just sightseeing, consisting of sunscreen, a floppy brimmed sun hat, sunglasses, refillable water bottle, energy bars, a stuff bag nylon windbreaker, and a small first aid kit.

• Stock your bookshelf with a selection of field guide books: deserts (such as Audubon’s Deserts), southwestern wildflowers, western or local regional bird book, desert wildlife (though the Audubon book has a wildlife, bird and wildflower section), desert plants, and a regional or state tour book like Lonely Planet or Moon Travel guides. Mike and Terri Church’s“Southwest Camping Destinations” lists all the campgrounds and related information for the Southwest. Edward Abbey’s “Desert Solitaire” is a good read also.

• Jerry jugs or inflatable water bladder for extra drinking water.

• If you plan on staying into April or beyond, when it heats up again, buy windshield and side window sun screens to keep the inside of your RV cooler.

• Sturdy-sided walking shoes or hiking boots to protect your ankles from cactus thorns and rattlesnake strikes. (I’m kidding about the snakes — they hibernate all winter, as do scorpions and Gila monsters.)

• Leave your ear plugs at home or you won’t hear the quiet — or the coyote serenade. And turn off your porch light if you want to see the spectacular Milky Way, as clear and sparkling as you ever imagined when seen through the clear, humidity-free desert air.

Tune up your RV fridge for better food care


By Greg Illes

The Norcold and Dometic RV refrigerators are ubiquitous, and RVers who live away from AC power a lot of the time really have few other options. By and large they do the job, given their less-efficient (than house-style compressor types) gas-absorption technology.

However, there are several problems that can exist even in the best of RVs. Addressing these issues can help these little units live up to their (limited) potential.

INSTALLATION — The manufacturers are very particular about clearances in the dark area behind the fridge proper. These clearances are essential for proper airflow over the coils and fins of the thermal structure back there. Unfortunately, many manufacturers either don’t try very hard or their production quality is inconsistent. The end result (as I found in my RV) is that the clearance specifications are badly violated. It’s not difficult for a reasonably handy person to pull the fridge out, take some careful measurements and fabricate some trim to establish proper clearances. This way, the airflow can work as the designers intended.

FAN (cooling unit) — For standard fridges with roof vents, there are usually no fans installed. For my side-vent fridge (it’s in a slideout), there was one factory fan. The fan is thermally switched — to put more air through the enclosure if the top coil gets too hot. On warm days, my fan used to stay on for hours and hours, using up battery juice — and the fridge would still be several degrees too warm. The solution was to add one more fan. Now, the extra air flow really cools things down. The fans now stay on for typically less than one hour; and even though the current draw is twice as much, the result is better refrigeration and lower current consumption. Even if you don’t have a stock fan, adding one in could give your fridge an extra advantage. It’s fairly simple to do by tapping into the 12V circuit and using a standard thermal switch.

FAN (fridge compartment) — It’s well known that air inside the fridge is not at a uniform temperature from side-to-side or top-to-bottom. Several aftermarket battery-powered fans are made for “stirring” the inside air, and they all work so-so. Reviews generally speak about unreliability and quick battery exhaustion. Since the concept is sound, adding a permanent 12V fan is a set-it-and-forget-it solution. Caveats: You will have to drill and seal some small holes in your fridge, in a safe place. You should select a fan with fairly low current draw because it will be on whenever your fridge is turned on. I picked a fan from Digikey that draws only 1/8 of an amp, which equates to 1.5% of my battery capacity per day. (Less than one cell phone charger.)

Tackling any, or all, of these tuneups can make your fridge seem almost as good as a household compressor-style unit — so be handy, have fun, and keep your foods and drinks fresh and cool.

Coffee-can your sewer odor away

By Russ and Tiña De Maris

If your RV is connected to a sewer drain most of the time, you probably keep your gray water valve open. This can lead to a smelly little problem: Sewer gases arise from the sewer hose into your gray tank, and slowly migrate up the through the tank and out the roof vent. At times those same evil essences can somehow reinfiltrate your RV with a negative impact on your olfactory organs.

Worse still, if there are any “vague” connections in your gray water venting system, those nasty little essences can also make their creepy way out, carrying not just the odor of gray water (as bad as that is!) but with a direct connection to the city sewer (or local septic system), that really horrific scent of black water can invade your premises.

What to do? Enter the Folgers P-trap solution. If you leave your sewer hose connected and the dump valve open, stick a P-trap between the sewer and you. Simply obtain a coffee can (or a large rock) and make a bend in your sewer hose. Gray water will advance over the bend, but the water trapped in the hose on the “rig side” of the coffee can will prevent the odoriferous fumes from crossing over.

Mind you, when you dump your black water you’ll want to temporarily remove the coffee can to allow a free-flow of black water, et al, to make the trip down the sewer unimpeded. One more thing: If your travels take you to the cold country, don’t use this lash-up in below-freezing weather — you’ll get more than just stink back!

Keep your toilet flowing when the freeze sets in

0

By Russ and Tiña De Maris

With cold weather “now in progress,” one RVer asks: How can I keep my tanks and water lines from freezing up in cold weather? It’s a good question, and one we learned about early in our RVing days when we woke up one frosty morning to find our water line looked like an icicle.

frozen pipe signWhen it comes to freezing up your RV, the first rule is: Don’t let it happen. Freezing water in a line is expanding water, and it will likely cause damage. Let’s look outside first. When nighttime lows drop below the freeze point, most RVers abandon any idea of hooking up a hose to their “city water” inlet. Fill the rig’s fresh water holding tank and let your RV’s water pump keep water at the ready. Of course, it’s critical that you keep the RV warm — keep the heat on to keep the rig’s water lines from freezing up.

If you’ll be in camp for awhile and have electrical hookups, some RVers have kept their water hose ice-free by carefully applying “heat tape” to the hose. Heat tape is typically sold in hardware stores to be wrapped around pipes at home to keep them from freezing. When using it on a hose, the trick that’s said to work is not to wrap the hose with the heat tape but, rather, run the heat tape parallel with the hose and tape it on. We’ve never tried it, but some say it works. And it may, provided it doesn’t get too, too cold.

Next, there’s the matter of the sewer hose. Again, if you’re in a park with sewer hookups, we typically recommend leaving the black water valve closed and allowing gray water to flow freely into the sewer. Not good advice in cold weather. Keep both valves closed, and dump only when your tanks fill up. If you’re in serious cold country and your tank valves are not in a heated basement compartment you may find them “frozen shut.” We’ve dealt with this by carefully pouring hot water over the valves to unstick them.

What about holding tanks? Again, if your rig is “winter ready” the tanks are probably safely tucked away inside a heated compartment. Only our truck camper has ever had this option, and we’ve always had to deal with exposed tanks. In our experience, if the weather warms up above freezing by day, we’ve always been good. But if you’re dealing with protracted below-freezing days and nights, you’ll need to do more. If you’re stuck in a cold-weather area, skirting around the rig may help keep some of the cold out. Hay bales are easy, but they mold and attract vermin. Using “real” skirting may be your only option.

Even with skirting, if there’s a danger of a holding tank freeze-up, your last viable option is a holding tank heater. Think of it as an electric blanket for your tank. It sticks on the bottom of the tank and uses electricity to warm the tanks above the freeze point. One manufacturer has a “dual power” system that uses shore power when in camp, and 12-volt power when the rig is under way. At about $100 per blanket (meaning two for the typical RV), it’s not an inexpensive solution.

If cold weather is severe, be concerned about keeping your inside pipes warm, too. Typically basement storage compartments are heated with your rig’s LP furnace. If you try and conserve LP by turning it off and heating with a space heater, you’ve blown keeping the storage compartments warm. We’ve found in really cold weather that it’s best to open the cabinet doors to areas where water pipes run to ensure warm air gets to the precious plumbing.

As a general rule, it’s never a great idea to keep your RV in the open winter air for the season. Look into RV self-storage units in your area.
