I had a small trailer, Heco pop-up roof, that had the window AC from the factory just like this pic, minus the clever luggage, which would have been a great addition.
I never knew the btu, but it was small and I think my 2200 gen ran it.Even with the tent sides it would cool the upper bunk just fine. I eventually added some cardboard to help shoot the cold air (off the top of the unit) up and keep it away from the lower intake.
Poor design did not always drain water off and when the trailer nose pointed down and AC had water in the pan it would leak on the floor. Most ACs have the pan fill with water and the condenser sits in the water to help cool. Great for a house, bad to have a full pan of water in a camper. I poked holes in the pan and tilted the AC unit more away from the camper. Rot was not too bad and the fix was possible.
Anyway, this is why I know little Ac units would work for my situation.
I'm still debating the whole AC thing. I hate to buy from Amazon anymore, looked elsewhere and found a Coleman 9200 for $613, so this brings me closer to maybe thinking about a small roof unit again.
We will see in the next days if my roof will hold the weight…
Debate is all over the place if a 2200 will run a 9200btu at all altitudes (at least under 6,oooft)…
Not sure about the debate on which gen will run which AC. I know for a fact that my Honda 2000 will start and run my 11k roof air when the tempature is in the 70's, some place between there and the 90's it fails to start the AC so is not dependable. Yes I have a hard start capacitor in the 11k unit.
LRA is the important # in AC and small generators. Locked rotor amps is the momentary power it takes to start a motor from a dead stop.
The 11k Coleman PS (power saver) has an LRA of 45.6. The Coleman Cub has an LRA of a whopping 58.4. So me personally would not buy one expecting it to run on a small generator.
There are a couple other options, one is the Dometic start kit and the other is the MIcro Air. I cannot recommend the Micro air as I have not used one, but there is enough data in that I would spend my money on one.
