If you have a truck camper, you probably have a smaller A/C unit than a travel trailer has. My small trailer has an 8000 btu A/C unit. With my 2800/3100 generator in economy mode, I get a small blip of RPMs when it first starts, then it settles really close to idle. So if you do have a smaller A/C unit, it should work. Rent a companion (Yamaha) generator and the parallel hookup for a few hours or a day and try it out. You may have to purchase the parallel kit. But that beats shelling out big bucks for another Yamaha and finding out it doesn't work like you want it to.
