Just thinking out loud.... Wouldn't it be nice if you had a diesel generator that would plug into the aux tank in the back of your truck? My 8000 watt runs .25 gals per hour at idle and .50 gals per hour on half load. Couple cons would be weight and if the truck had to be at the RV to run the generator. The pro would be being able to run 75 to a hundred hours on a 50-gallon tank aux tank in the bed of your truck.
