Depending on how you want to use the generator why hook it up permanently at all? It was made to be portable so why not just get a cord that goes between it and the inlet to the RV, use the compartment as transport only and when you camp, put the generator outside and run it there as it was meant to be. Of course these puppies are noisy and you're not going to make many friends but they are not designed to work in an RV compartment, or any enclosed space at all. By the time you get done playing your going to have a cheap, fail-prone generator that you spent three times as much money trying to get to do something it wasn't designed to do. I too had this idea but after much research (Among other things I'm an engineer.)shelved it in favor of a rebuild of my old one. Balanced the crank, new pistons, rods and rings, honed it. Purrs like a kitten and does the job as designed. Just remember, sometimes you eat the bear and sometimes the bear eats you. This is one of those times.
