As Brian posted, a "true 50 amp generator" (for RV use) would be a 12,000 watt generator. That is in the "range of a "midsize home emergency generator set" and would be impossible to transport with most any travel trailer or fifth wheel. Even a 30 amp 240 volt generator (to connect to a 50 amp RV plug) would be a 7200 watt running/9000 watt starting power system. That's one like the generator that George posted (Champion 100161) weighs in a tad over 200 pounds, sports a 15HP engine (burns about 8 gallons in 10 hours) and takes up much of the bed in a "standard bed pickup"....

Most people "make do" with either a pair of 2000 watt generators, a pair of 2500 watt generators, a single 3500 watt or for the "power users" a pair of 4500 watt ONAN generators paralled to provide a maximum of around 37 amps of 240 volt power. Even that system weighs in at 100 pounds (dry) per generator, so 200 pounds before you add fuel, which is around 7 gallons to fill both. Then add the parallel kit and you're again, taking up half the truck bed and over 200+ pounds of heavy generator.

As suggested, stick with an "enclosed, sound compensated inverter" type generator. If the description includes "open frame" it will produce significantly more noise than your "campground neighbors" will tolerate. Be "campground friendly" and limit your generator selections to "enclosed inverter models" and then, only use them during "generator hours"... Campground generator use is not a 24/7 event.

So, going smaller/lighter is not only space saving, it's "back saving" and more economical to operate.
