RV Selection & Electrical Question
Hello, I have a rather strange question. I am looking to buy either a class C or Class A motorhome (both used). Unfortunately, there is a complicating factor: I have toured both Class A and Cass C uni...

A full-time device with that much draw is not going to do well in a RV with 30 amp electrical system, if you intend to run air conditioning. Loads are going to be unpredictable with out a load manager (which rarely includes convenience outlets). The circuits you might choose to use may or may not have 6-10 amps available depending what else is running. You could probably make it work if you understood the 120V power distribution of each RV you considered buying, but information with that detail is seldom unavailable.
In a 50 amp rig, you will still have issues with which branch circuits you can safely use, which might be susceptible to other loads. At least you should not have to worry about the main. Many 50 amp RV rigs have one A/C and all the convenience outlet and "hard wired" circuits on one leg of the dual 50 amp, and the second (and third, fourth) air conditioners on the other. They also often have power management systems for running on a single leg. You will not see this kind of electrical sophistication in Class C RVs, more often it is a feature of larger Class A motorhomes, those large enough to need at least two conditioners for comfort.
