Thanks for all your inputs. I finally had a full length shelf on the rear and had it welded to frame and beefed up the hitch also welded to frame. I then mounted 2 onan 4500i inverter generators hooked to gather with the onan supplied wire harness. This supplies 50 amps. Both have remote controls. When ac is not needed I hook the original supplied cord to one generator for 30 amps which is totally adequate for power without the air. Fuel (gasoline) consumption has been good using 5 gallons for 8 day dry camp in AZ last week with no air. Plenty of tv during high winds at fireworks show. Happy so far. $1295/generator and $200 welding.
