Okay, I'll try again...
50 amps at 120 volts is 6000 watts. That is a lot of generator. Theoretically, you could parallel a couple of 3000 watt inverter generators and be good to go. A couple of hundred pounds and lots of space taken up in the bed of your truck. Not to mention many, many US dollars.
Me, I think I'd spring for a campground with 50 amp service.
Most of us run 30 amp service with a single A/C so a couple of EU2000i units work fine.
