Motor vehicles should have a minimum range of 600 km. That shows a 151 L tank, so at least 25L/100 km.
As for power, I'm not familiar exactly with how a motorhome provides power, but I'd think that worst case scenario you could run the engine if the batteries get low. I also think it's a good idea for novice RV users to get a site with power if possible; just to eliminate any doubt.
Worst case, double check when you pick up the rental and ask if the battery for the truck portion is independent of the battery for the RV. I think it should be.
