One of the recurrent questions asked by folks considering the purchase of an RV is very basic: Where should I buy? Here are the most important factors I would consider. Please note, my list may not agree with yours and is not in sync with conventional wisdom.

1. Unless I were a technician with a solid skill set or took a technician with me, I would not buy from a private party. Some private sellers are very honest; some are very dishonest, but unlike dealerships, private parties have no track record to maintain and some are not even knowledgeable enough to know what works and what doesn’t.
If you are thinking that buying privately will save you a bushel of money, unhappiness is sure to follow when the purchase price is low and the need for service after the sale is high. I might call this the “Yugo syndrome,” coined when that famous little import from Eastern Europe invaded the United States in the mid-’80s.
2. I would buy from a hometown dealership whenever possible. Even in this age of depersonalization, when shopping via the Internet is all the rage, there is much to be said in favor of buying close to home.
My reasoning here is twofold. First, hometown buyers are more likely to get hometown service. Why? Because they are the buyers who are most likely to return a second time. When I do service work, repeat local customers will most often find the first thing they hear when they call is that I answer by calling them by name because I loaded it in my smartphone. Like most dealerships, I have discovered repeat customers are the best customers and if they are close by, it increases the odds I will see them again.
Secondly, as a sequel to my first point, if you are committing to buying an RV, you are also committing to the inevitable service work that comes as part of the deal. Many dealerships service their own customers first. You may well save a few hundred or even a couple of thousand dollars by shopping on the Internet or buying hundreds of miles away, but if it takes two months in the middle of the camping season to get your RV repaired, the savings may not be quite so memorable!
3. I would buy from a small dealership rather than a mega multi-site conglomerate. I like personal service; I think most folks do. Small dealerships are more likely to remember me. With large businesses, I have too often heard the phrase, “It’s not personal; it’s only business.” Try to convince someone committing to purchase something with a long-term loan that it is not personal.
I know mega-site dealerships have a greater selection and sometimes getting what you want close to home is simply not possible. If that is truly the case, buying from a large dealership may make sense. More often, however, I see folks looking for a way to save money that in the end may not save them much at all.
I have three more points to cover, and I’ll do it in the next installment.



I guess we live in a throwaway society. My motorhome is only five years old and the toilet slide valve stopped closing completely. I tried to disassemble it and found that it does not come apart completely. Why would they build a unit that cannot be disassembled? I discovered that the problem was a buildup of calcium on the slide blade and gasket. There was also a lot of buildup inside the housing itself. Even though I was advised not to use Lime-A-Way, I did anyway. I had to keep spraying inside the housing and flushing it out because I couldn’t get a brush in very far. I am a retired engineer and have had RVs my whole life. This Thetford Aqua Magic V is definitely not Shadetree Mechanic friendly. I am writing to you to vent. It makes me feel so much better. Thanks for listening. —Another plumber, but not Ralph
The answer may be counterintuitive: Add a little noise.
But when you have to make a purchase choice, what kind of generator will you buy? While there are really three major fuel forms for generators, gasoline, propane, and diesel, the latter is typically only an option when you’ve got a diesel fired motorcoach. Don’t discount diesel, will come back to it.
I recently purchased a toy hauler with a generator with only 27 hours on the meter. At first the governor appeared to be sticking, due to what I believe, bad fuel (varnished). I sprayed the carburetor with a cleaner and it ran fine for a while. The idle still surges with no load applied, and if I put a heavy load on it, it seems to get better. The butterfly plate at the front of the carburetor, when pushed down manually, makes it run smooth. Any ideas? —Mike C., Newbury Park, CA
Prolonged surging is indicative of a governor and/or carburetor out of adjustment. Unfortunately, the carburetor and governor should only be adjusted while monitoring the voltage and frequency and while applying a measured load at the same time. In other words, RV generators cannot be
tuned by ear. As I often state in my seminars, every mechanical adjustment on an RV generator carburetor and governor will have a direct electrical result, so I don’t condone any tweaking and twisting by RV owners. I’d recommend a generator set-up by a certified technician using a properly sized load bank (see photo). Some individual RV repair facilities may have such a diagnostic load bank, but you’re best bet is to take it to a certified shop for your brand of generator when possible.
One of the most vulnerable spots on our coach is the quad headlight installation, which consists of expensive, and difficult to replace, Hella halogen units. Chipping or breaking one of these puppies would be inconvenient at best.
Reader Terry Weymouth chimed in on the idea. Writes Terry: “Storage space under the bed is a great idea … until you need to get something in the dark of night. It is dark, the ceiling lights don’t shine under there and a flashlight requires one hand to hold it (unless you hold it in your teeth).”
You also need to “water” your batteries from time to time. This means that you “top off” the cells with distilled water. Always use distilled water because the minerals have been removed and will prevent CBU (crud build up) on your battery plates. To do this job you will need distilled water, a turkey baster, eye protection, a flashlight and some paper towels.
