My experience with a coleman Mach series, even with the soft start cap, It won't reliably start the AC. yes, when your at sea level, outside temps in the 80's good chance. But when the temps are in the 90's, or your above about 1000ft, your likely out of luck.
Now some of the newer 13K/15K units are designed with much lower starting current, as in the coleman power cub 9KBTU. That one I can reliably start and run at 7000ft in the 90F range.
Some have said the dometic AC units start more reliably but it's still iffy.
And then to get it to start you MUST turn off ALL other 12V devices, including the battery charger/converter and be very very carefull of what you turn on after it starts running. Basically, if it starts you will be cool but in the dark and even the water pump can kick it off.
IMHO you either need two honda's or something bigger to start with.
