We boondock
A LOT, and I use a portable generator with my fiver. I just put in the back of the truck to haul it and leave it on the ground to use it. I move it several feet away when it's running so exhaust fumes aren't an issue. If it looks like rain, or we're leaving for a while, I shut it off and slide it under the trailer and lock it up. Trying to mount it and run the associated exhaust system, etc would be far more trouble than it would be worth.
It's a Chinese knockoff, and I paid $249 at Pep Boys for it. 3500 watts max, 2750 running. It will run the A/C just fine, as long as nothing else (other than the batt charger) is running at the same time. If no A/C, it will run the coffee pot and everything else at the same time. No, it isn't as quiet as the Honda units, but it didn't cost a small fortune either....and it's usually one of the quieter ones I encounter at most campgrounds. You can have a normal conversation standing 3 feet away from it.
I've been very happy with it. I'm sure the usual Honda pundits will chime in and disagree...more power to them. The $800 I saved will buy me a lot of camping and I will still have more power than them...unless they feel like popping another $1100 and buying a second one to tie in tandem with it..... And if I do have a fussbudget at a campground that says it's too noisy, I will promise to turn it off if they will promise to keep their yappy dog quiet
First peep out of their of their little runt, and back on it goes. (Settle down, I'm kidding.....maybe)
Our favorite campground in Cloudcroft has "generator hours" and "quiet hours". The camp hosts will give you a nasty scowl if you run your gennie during QH. I wish they had yappy dog hours too. Kidding, of course.
