I sort of disagree...electric propulsion for an RV IS feasible. I worked at Hyster for a decade designing and operating wire guided electric forklifts. We had forklifts that would work 8 hours long, weighing in at 33,000 lbs, and operating on battery only. (Though the top speed was limited). HP in the 200-250 range. Using a GE EV-1 speed controller for efficiency.
So with that background, I've often thought it would be pretty easy to remove the diesel engine and tranni, add a forklift battery pack and diesel generator, and 250 HP DC motor, and using the EV-1, head on down the road.
I'd love to work on this project. You set it up Futureboy, get us some investors, find a shop in the Mojave desert, and I'm in. A used diesel chassis shouldn't cost much. There's lots of big empty shops around Edwards AFB too.
From a standing start, a 250 HP motor would draw 2600 Amps from a 72 volt battery. Once rolling, it wouldn't need but a 10th of that...260 Amps. Hmmm. Where's my scientific calculator??
BTW, OP, the software to control even a forklift was NOT trivial. Tens of thousands of man hours of development went into the software rich EV-1000 when GE upgraded...we rejected it. It didn't work worth a **** and their software engineers couldn't get it to do what the old EV-1 analog system did easily.
