The closest I can find is an open frame (contractor generator) rated this way:

GAS-- 3400 surge/3100 sustained
PROPANE-- 3060 surge/2790 sustained

The Manual for that generator states that output power is reduced 3.5% for every 1000' of altitude.

So, assuming your generator has similar output as this one AND you're running it on propane at 3000' elevation, you're looking at a reduction of 10.5%, giving you an estimated output of 2738 surge/2497 sustained.

2500 watts is 20.8 amps. That MAY be enough to operate your air conditioner and the converter/charger, but I'd worry about voltage drop and burning out the compressor in the air conditioner on a hot day....

If it were my trailer, I'd not use that single generator and honestly, if the cabin has a 20 amp outlet, plugging into that isn't a lot different than running the generator on propane at altitude. Neither will power the trailer for the "long haul weekend".

buying a second generator to parallel may be an option, but that may cost nearly as much as just buying a single generator in the 5500/4500 watt range. To be honest, I don't think I'd buy another generator for a single trip. I think being in the mountains, during the day, you'll probably be outside anyway, and at night, with the windows in the trailer open and a fan or two to move the air, it should be cool enough to sleep without the air. You really don't want to run a generator overnight anyway, mainly because of the noise and the risk of starting a fire or annoying the cabin occupants with all the extra noise while they're trying to sleep.

I think I'd look into the possibility of setting the trailer close enough to the cabin to plug into an available 20 amp outlet, set the refrigerator and water heater to gas, skip using the air conditioner and the microwave, open the windows, turn on a fan and enjoy the "mountain breezes"....

Hi John,
If our mountain host only has 15 amps will that be enough to charge our battery? We hope to run our 12v dc refrigerator, a few lights and maybe a bedroom fan on the 15 amp circuit. If I get lucky maybe he has 20 amps circuit. Not sure yet.

And is it okay to go from the rv’s 50 amp dog one to 30 amp and use the 110 adapter?

Also, can I use a battery charger while running our RV on battery power only? Or is that a no no!? Thanks Dom
