I highly recommend the Coleman Power Saver 13.5k 9xx series units (not the older 8xx series). Some of these units have LRA's as low as 50a and can be started/run by one Honda EU2000i.

A little HOnda can start and run a 13.5K btu AC, but not dependably . . .

All 13.5k BTU a/c units are not created equal. There is a specific reason why some 13.5k BTU a/c's can be reliably started/run with a solo Honda EU2000i while others cannot.

The closer a given 13.5k BTU a/c unit gets to 50a of LRA, the odds of a EU2000i reliably starting/running it (with the Eco mode on) go up dramatically.

FWIW, the vast majority of OEM 13.5k BTU a/c units have 60-68a of LRA---too high for a solo EU2000i to start/run reliably--even with the Eco mode off.

That is consistent with my tests. I was able to reliably start and run our Coleman 13.5 PS with our EU2000 in 97 deg ambient temp.

Thanks for all the post. Since the Arctic Fox is so well insulated, the 13.5 works well. I run it off 2400 Yamaha inverter with no problems(I don't use much else besides lights and T.V.). We'll be taking this information when I need to replace it. The unit is 10 years old.

Dave (the OP) ... I see that your RV may be about a 30 ft. trailer?

If you were happy with the cooling capacity of the 13.5K A/C unit that was in it, I'd recommend replacing it with another 13.5K unit - but one of the new high efficiency models.

If you drycamp at all, a high efficiency 13.5K unit probably will start and run fine off only a Honda 2000 inverter generator. This a nice way to drycamp comfortably in warm weather using only a relatively small light-weight and fuel-efficient generator.

Dometic Brisk Air, model 57912.602 LRA 48.3. Works well in cool weather, will not start and run in hot humid weather with hard start capacitor installed with eco mode off. I am in SW Fl at 10 feet
elevation.

Which AC are you running with your HOnda?

A friend of mine has had great luck powering his Coleman Power Saver 9xx series 13.5k BTU a/c with his solo EU2000i. LRA on his particular unit is 50a.

As for your Dometic, it would be helpful to make some inrush current tests using both commercial power (to establish a good baseline) and generator, to determine whether your a/c unit, wiring/connections, or generator are performing properly.

Why Upgrade. Well It's getting hotter out every year, Record breaking heat waves.

Now: What's wrong with your A/C.. in my case it was catastrophic failure of the cooling uint. (THe part that is above the roof) Carrier (Mine are Carrier Air Vs) no longer makes RV air conditioners so a direct replacement was not possible (Having seen how they bungled my unit (Died of a factory error) I'm not surprised they left the field)

I was able to get a "Drop on" replacement though. Mine is Advent air (I do not recommend) I believe one of the companies that start with "C" also makes one that fits. What I forget is which company.. But a good dealer will know.

Curious why you would not recommend the Advent? I have been watching them for a bit. Jim

My Honda will start and run my 11K AC with a hard start capacitor when it is cool but not when the tempature is in the 90's with high humidity!
