A/C compatible with 2000 watt Generator?

The Mach 1 would be 1188 watts (9.9 amps @ 120V)
The Polar Cub would be 1332 watts (11.1 amp @ 120V)

2000W gen should be able to run either one.

Sorry for the confusion. I am getting a 6x10 v-nose trailer and making a camper out of it as well as a motorcycle carrier. For about $6k I can get it outfitted by the manufacturer with insulation, sheathing, a/c, windows, etc. and put in a folding bed/sofa sourced from Blazin' Belltech. I'll put a counter with sink and place for the Coleman stove in the nose so I can cook out of the weather if necessary. I would like to source an a/c that could be adequately powered by a 2000w generator although that would be rarely done (just wanting the capability if necessary). I mostly stay in state or national park campgrounds without hookups and they usually have generator sections with generator running times. So if I want a little relief from the heat I can crank up the a/c for a while. I am a solo traveler so have simple needs but I also want the availability of secondary transportation other than my Chevy van tow vehicle.

As a third possibility, you can get a Danhard AC unit which doesn't stick up on the sides or the roof, just has a vent. They are expensive, but I'm sure they have a model around 11,000 BTUs that can be run with a 2000 watt Honda without issue.

He is adding the AC to a 6X11 utility trailer. He said nothing about camping or RV parks.

haven't seen an rv park that allows gensets in 14 years so far.

I would hook up if 120v was available in the RV park. In no-frills parks (national, state, etc.) usually they have a generator section and I would just be looking to knock off the early evening heat while cooking and eating dinner.

Without being able to do an engineering study, I would guess that a "window" A/C like the one pictured above would direct more noise to a coach parked right next to it. A rooftop should direct some of that noise Up and Away. Now if the setup also included a genset running, the genset just might be the noise factor.

The Coleman 9000 btu low profile gets my vote for a small trailer.

Easy to run on a 2000W generator.........big enough to cool that trailer down

I have run my WESTPOINTE 8000BTU 120VAC Window Unit many times on camping trips using my 2KW Honda Generator. Sometimes the kids will follow us somewhere and we set this up in their tent setup sitting on a wood shipping pallet at a second door entrance.



Works great... Of coourse the bigger problem we usually have is finding a public camp ground that would allow us to run the generator for long periods of times here on the east side of the USA..

I suspect the 9200BTU COLEMAn MACH low profile roof RV air conditioner would work just fine as well...
