RV Electricity – Just Ask Mike (J.A.M.): Getting ready for the road


By Mike Sokol

Welcome to my J.A.M. (Just Ask Mike) Session, a weekly column where I answer your basic electrical questions. If you’re a newbie who’s never plugged in a shore power cord (or ask – what’s a shore power cord?), or wonder why your daughter’s hair dryer keeps tripping the circuit breaker, this column is for you. Send your questions to Mike Sokol at mike (at) with the subject line – JAM.

Dear Mike,
I attended your seminar in Boston. I don’t yet own an RV, but part of my education was to attend some seminars. By far this is a must! I joined your page (even though I am not an electrician), I purchased your book (paperback) and the basic 3-piece meter kit you recommended. As I continue my RV search, I will continue to read and ask questions based on what I learned at that basic seminar. Thank you for saving my life. I never considered this part of RV ownership. —Rick

Dear Rick,

Thanks very much for the kind words. Yes, I think you’re 100% correct. Just like the captain of a ship or pilot of a plane, you are responsible for understanding at least the basics of how your RV works. And that includes all the plumbing, electrical, braking and towing systems.

I am constantly amazed at the number of new RV owners who contact me after a few days of their first outing, and they can’t figure out how to make things work such as turning on a water heater or adjusting the brakes on the trailer. That’s not only dangerous, it puts a crimp in your vacation plans and can spoil what otherwise could be the first of many camping adventures. So a few pieces of advice from an old road dog.

Roads#1)  Camp in your driveway or backyard first. Or better still, find out if the dealer you’re purchasing your RV from will let you boondock in the lot before you leave for home. That way you can ask additional questions and get more advice in the morning. Don’t set out on a 5,000-mile journey as your first camping trip. Try it first close to home. All good bands know this and rehearse their shows before they take them out on the road.

#2)  Make sure you take enough stuff. Yes, I’m often accused of over-packing, but when you’re 3,000 miles from home, like I am a lot, I don’t want to be chasing down simple items I could have brought from home. While carrying extra weight can be a worry, you still want to bring more than you think you need. Believe me, you’ll need it. There are tons of lists online that show what you should pack for basic tools, kitchen utensils, electrical meters, tire pressure gauges, etc.

#3)  Weigh it all before you hit the road. Scales are cheap to use and you’ll never regret knowing your weight. Find a CAT scale at a truck stop, or better yet a weighing service that will show you the load on each tire and axle separately. And understand the proper tire pressures, tongue or pin weight, etc. Roger Marble has some excellent tutorials here, so study up and be safe. Knowledge is power.

#4)  Know your rig height – and write it down on the dashboard of your vehicle. There’s a ton of videos out there showing newbie RV owners peeling off their rooftop air conditioners (or worse) on a low underpass. And force yourself to notice all height signs at bridges and underpasses. Don’t be the next guy in the video.

#5)  Get some basic electrical test gear and learn how to use it. Yup, I’ve written a ton of articles here about how to use a meter to measure voltage, current, wattage, etc., and what to expect for battery life when boondocking. An RV is not a house and you’ll have to learn to adapt by not running your daughter’s 1,800-watt hair dryer and your kitchen microwave at the same time. All you have to do is hit the search button at the top of every page on this site and enter “Sokol” or “Hot-Skin” or “Generator” or whatever. I have well over 300 articles published on this website alone, and I’ll bet you’ll find answers to your question in at least one of them.

#6)  Purchase an EMS/Advanced Surge Protector. It’s cheap insurance that you’ll never regret. Plus get enough adapters to power what you want from whatever you find available. While the electricity at your house or a local campground might be just fine, there’s a lot of really shaky power out there. Don’t be one of those families who destroy their RV’s electrical system by plugging into a miswired pedestal. That can take months to fix while your RV sits in a shop waiting to be repaired.

#7)  Enjoy the journey. It’s not about how fast you get there, it’s about what you do along the way that counts. While I’ve done 3,000-mile solo drives in 3 days (seriously, I have), that’s not enjoying the road at all. That’s me doing a rocket launch across the country. Sometimes I have to do it to meet a tight teaching or production schedule, but I’m much happier with 300 to 400 miles a day. That gives you more time to smell the roses, barbecue or whatever.

OK, everyone. Remember that electricity is a useful and powerful force, so we all need to pay attention to safety precautions while using it.

See you on the road. Let’s play safe out there….

Question: a friend just sent me the following question. “Have you ever checked the “torque ” on the connections to your breaker panel in your RV?” I immediately went out to my motorhome and noted the switches and fuses were visible but where were the connections? I had never heard about this ‘maintenance check’ so never addressed this issue. Looked closely and determined I had to remove the breaker panel to see the connections. There they were. Checked them all – everything nice and snug. Why no info on this preventative maintenance subject? A good link to see what this is all about: Check Your RV Electrical Service Panel Screws

If by chance your first outing is a long remote one, remember that we’re out here to help if you need it. Most of us are ready and willing to lend a hand.

Camping in your back yard – BEST advice ever. We STILL do that every year for our “shakedown” cruise. This year we had a bad O-ring on our kitchen faucet. Leaked like a seive. Replaced it and life is good.
