My old camper had a window unit (from factory), it was small so my Ryobi 2200 inv generator would start and run it just fine.
My current ac is a 13500 roof unit, that will not start with the gen, even with a SPP6 Hard Start capacitor installed.
My AC is over-kill as it is. I would like a smaller roof ac that can be run on the generator.
I have a nice receiver plate custom made for this generator and it is at the front of the truck, and works perfect being small and lockable. A bigger gen would not be so slim and uses more fuel etc.
Preference is to change ac, not generator, and I think ac is cheaper than a quiet gen…

I have heard of 8,000btu root ac but not seen one. Any experts have done this mod?

not looking for knee-jerk reactions or comments, just really knowledge or has-done-it people. thanks.

Coleman makes a 13,500 BTU PS (Power Saving) model that requires significantly less power than does the conventional Mach 3+ model. Regardless, replace that next-to-useless SPP6 hard start cap with a Micro-Air Easy Start Soft Starter Kit that will significantly improve starting & running your A/C with a 2K genset. In fact, you might invest in an Easy Start first - who knows, you may be surprised to discover that your current genset will start the A/C just fine.

We have the Atwood Air Command 13.5K BTU Non Ducted AC as a second air-conditioner for our 35ft. motorhome. I like it better than our ducted air.

YEARS ago, they made 11k and 8k RV roof AC units. They stopped making them because they did not sell that many. I would stick with Dometic or RVP(Coleman). Other brands are basically orphan units, even Atwood(owned by Dometic). The model listed below is a LOW POWER RVP 13.5 which should do the trick for you. Doug

•Running Watts Desert: 1320

The Coleman Polar Cub 9200 is a smaller A/C, and I've seen a number of posts by people claiming it starts and runs just fine on a 2,000 watt genny. As far as switching it for a bigger one, as far as I know, ALL A/C's mount to the same 14"x14" roof hole.

I don't think your Ryobi is living up to its rated wattage.

https://www.pplmotorhomes.com/parts/rv-a........h-8-ultra-low-profile-9.2k-white_08.0212Coleman 9200 btu Polar Cub should fit the bill, though the bad part is the 13.5k btu models are all your best bang for the buck.

have a polar cub in my small trailer. it will easily start and run from my honda 2000 even at 7000ft altitude and no mods to the AC unit. (no soft start cap added etc). IMHO it's a nice unit for smaller trailers and I wish the mfg would use them more on small trailers.

You may regret swapping out for a smaller A/C in another year or two. I know I'm glad I upgraded mine (13,500 to 15000) and wish I could upgrade even more.

But there are smaller ones (others have pointed) you might also, if that Robi can be "Twinned" and parallelled go that route. Makes it possible to use electric coffee maker and A/C at same time (Or other kitchen stuff)

Just now I'm on a well shaded 50 amp site so for the first time in a while I'm staying cool all day. No sewer (But I won't be needing to dump till my next stop and that will be full hook up) but nice and cool!!!
