Coleman Mach III 13.5 btu replacement

after 11 years, my ac unit gave up the ghost.

I have run my ac on my honda 2000 - but when it's really hot (above 90) it's exceeding my Honda's running capacity.

The Honda's rated output is 13.5 amps at sea level (with a 16.6 amp 20 minute 'burst').

I know, I could buy a higher rated generator, but I don't need the AC that often and if I could get away with a higher priced AC unit that would draw less amperage, maybe it might be enough.

how much less amperage will a power saver reduce the amperage consumption on a replacement Coleman Mach III PS?


thanks in advance,

Josh

    outstanding!

    Thanks all for the insight.
    I'll start with trolling through the specs from the document library.
    From there i'll start making decisions.

    We're not going out in the 5er at least until October - so I have time to figure this all out. We're finishing the RV Makeover - and i'm planning the next phase of the update.

    Take Care all and thanks for the suggestions!

    coleman has a 13.5K version that draws less current and has better (lower) starting current and LRA spec's. That's what I would go for.
    Check out the 48208C966, one of Coleman Mach's most efficient 13.5k BTU ac units. More than likely you'll have to special order the 48208C966. They're rarely stocked by RV distributors. Dometic can't come close to this unit in terms of efficiency (BTU vs. LRA/continuous current). It has a 50.5a LRA rating and a continuous current draw of ~11a under "desert" conditions---both excellent specs. Most 13.5's (especially Dometic) have a much higher LRA (60-68a) and a higher continuous current draw of 13-15a.
