“ I've found even at 8000ft I can start the AC with the generator in eco mode w/o any fuss. But then I don't have a inverter transfer system in place.”
That’s good news…What size is your air conditioner?…Easy-Start??

Several dry campers we know including us have installed the easy start on 13.5K BTU AC units with very good results. However I will point out one thing to consider regarding the honda 2000 and the easy start. The honda 2000 engine is pretty much max'd out so output max power goes down with altitude. We found that around 3500ft density altitude the 2000 is likely to overload, luckily the easy start just shuts the AC down for about 5 minutes rather than having the honda completely kick out. This is with all other 120V loads including the converter power turned off.
solution honda 2200. it has a much larger engine and even at 8000+ft it can run the AC unit and still have about 300watts to spare. As a check with a honda 2200 we ran our AC at around 8000ft in 100F temps and I turned the fridge on AC just to see what would happen, 2200 kept on running, no overload.
Before the easy start I was lugging around two honda 2000's, paralleled for AC, when the honda 2200 came out i bought one, gave one 2000 to our son, and for a while carried around a 2200 and 2000 as a "just in case" for AC when boondocking. Gave that up, never have needed more than the 2200 even at very high altitudes. Solar charges the batteries,
Agreed, me too…At high altitudes and temps (100d/f) my 2000 struggled - Eco mode was not an option…The difference between the 2000 and 2200 is much more than just the 200w, mainly because of the 2200’s larger GX commercial engine and viable Eco operation…
However, I later discovered that my pass-thru PSW inverter was the single biggest culprit at preventing Eco mode operation because it would ‘disqualify’ in coming genny power upon compressor starts when in the (low RPM) Eco mode…
So after a ton of study and consternation, I did a workaround by adding a dedicated, corded genny-eco ATS switch around the ‘too smart’ inverter (at it’s output), and all was resolved, except that now with the LFP’s, solar and Easy-start I haven’t had much of a need to run the genny for quite some time…I still carry it just in case…

Well FWIW, with our onboard converter-charger switched off, the 2200 Honda runs our 11kbtu Coleman (with Easy-start) in Eco without a hitch - but my understanding is that what happens (at least with a single Honda) is that it’ll handle brief excursions to max wattage (say to 2000w), but rated at 1600w on a continuous basis

On a slightly different note, motors do tend to draw more running amperage after initial warm-up (20 or so minutes), and at temps rising above about 95d/f, while altitude will slightly de-rate generator output…

We have two Honda eu2000i generators paralleled running a 15k AC. Honda generators paired like this will only provide 4000 watts for first thirty minutes, then they dial themselves back to 3200. The 15Kbtu requires 3800 watts for initial start, so test failed about 40 mins in after about the 3rd or 4th kick-on.
Soft start should reduce this below the required threshold. Parts are on order, should be here within the week and we'll do another test after installation.
An additional note, with our two eu2000i Honda's, with AC running we were able to put up the satellite and watch TV too, but as I said, after 30 min the power went down, but once the SoftStartUp is installed, that will be resolved.
Well, it’s not clear to me what you mean by “the power went down”, but (assuming no other loads) if your talking strictly about the 15kbtu air conditioner, I’m a bit surprised that the two Honda’s couldn’t momentarily surge to 4000w (per their spec’s) to handle this uber brief compressor start surge, maybe this was while in eco-mode (I donno ??), but it sounds like more info is needed…Yes, Easy-start will help out…
