The motorhome will have a LP gas Onan... however, with 10 gallons of usable propane in the tank, I'll get 20 hours out of the Onan before it conks, which means it will last two days at best in the Texas heat. For 3+ days, I have a Yamaha 3000iSE, and several five gallon gasoline cans, and that would go on a hitch mounted cargo rack.
My intent was to make sure, by some procedure, that the stuff in the gas cans didn't wind up anywhere than the generator, because I've seen two incidents of dead Sprinters killed by the wrong fuel. One of them was killed by gasoline, the other because someone added DEF into the diesel tank, causing ammonia to crystallize on the injectors, and destroying the entire fuel delivery system.
