Looking for LOWEST BTU Roof A/C available-

That spec sheet is for the 3PS via the link from another poster.

The specs for the 11,000 BTU 9XX Series Mach 1 you mention is:

Mach 1 9XX Specs

This is lower then the 3 so-called "Power Saver" units.

It would SEEM that my Honda 2000i might run it based on the specs-

These are the specs for the new 9200BTU Polar Cub Casita installs:
Polar Cub 9201 9200 BTU Specs
but many Casita users say their Honda 2000i struggles to start that one (plus due to higher fan speeds for use with R410A it's objectionably noisier than the OLD R-22 Polar Cub Series).

Strange that it is 9200 BTU in the 9XX Series you mention (and makes me wonder why Casita doesn't install the Mach 1PS instead), but the LRA is HIGHER (45.6) vs. the 11,000 BTU Mach 1 LRA at (41.5).

Confusing!

But Click Here is a thread where someone with a truck camper tried using the Coleman Mach 1 PS 11,000 BTU unit you suggest, and it worked fine (at cold temperatures) with a Honda 2000i genset.

I mention that because I noticed that my 5th wheel A/C uses OVER 15a at hot temps (116 deg ambient, but more like 145 deg on asphalt) and tripped its 15a breaker running, yet when the inside air cooled to the 80's (after the A/C had been running a long time) the unit was only drawing around 12 amps. (I've learned carry a clamp ammeter w/ me at all times).

The only way I could keep the breaker in was by pointing a fan at the CB panel until the A/C had cooled the RV interior down a lot. The coolest I could get it it in my 5er was about 87 degrees at the hottest part of the day, but that was AZ parked on an asphalt RV campground lot, a pretty extreme condition which I mention only because A/Cs take a LOT more current in high ambient temps (The Coleman chart in the link shows 25% more in desert conditions, in fact) .

There are still older, 8xx Coleman Mach 1 Power Saver 11,000 BTU's being sold. It's very possible the individual in this Nov 2013 link had an 8xx series Coleman Mach 1 Power Saver 11,000 BTU with a higher LRA.

FWIW (and it may be worth little--lol!!), I've run my 13,500 Dometic a/c with an LRA of 63 amps with one EU2000i with the ECO mode off. I have also seen one EU2000i power a 9xx Coleman Mach 1 Power Saver 11,000 BTU in southern AZ heat (108 deg day temps; 90 deg night temps) for 48 hours straight with the ECO mode on.

Ref your comments about changing conditions, if you click on the links in my first post in this thread, you'll note Coleman gives some specs under extreme desert conditions.

In any case, there are no guarantees, only calculated risks. As always YMMV.

Good luck!
