The older Honda EU2000i is only rated for 1600W continuous operation. The new Honda EU2200i is rated for 1800W continuous operation in the same size package.

I have a Micro-Air Easystart on My 15k Coleman in my 30 amp Class A. I can confirm its works very well. I put it on due to running my whole coach off my Magnum 3000 and the 70A
startup surge was causing the Magnum to occasionally complain even when on shore power due to voltage sag.
With the Easy-Start I can easily start and run the A/C off my inverter, it cut the startup surge way down. I have no real use for running the A/C off battery as I only have two Lifeline GC-4 AGM's and they will only run the A/C 30-45 minutes until 50% SOC. I can however greatly extend that by idling my V10 with stock 175 amp alternator, I normally just run the gas generator however.

A Honda 2000/2200 will run about 4 hours on a gallon running a A/C, its very efficient being a inverter based design. This is also the reason it varies RPM since its frequency output is not tied to the engine speed as it is with a normal generator.
A 10kwh lithium pack can run an A/C for 8 hours, you then need to charge it back up. If you use a 8kw alternator off the Mercedes Diesel assuming .5 GPH you end up at nearly the same consumption, perhaps a little more, but its coming off the vehicle tank rather than carrying separate fuel.

Half load 0.28 gph
Full load 0.46 gph

As a comparison the same generator using LP that the OP is promoting is only 2500W and its consumption is:
No load 0.3 gph
Half load 0.4 gph
Full load 0.6 gph
Propane is less energy dense than gasoline and gasoline is less energy dense than diesel.
I do wish Onan would do smaller inverter based designs, their QD 6000 and 8000 are inverter diesel and very efficient.
