I looked on the web and I can see that Coleman makes up to a 27KBTU
12/120v rooftop AC for rv's but I couldn't find a source. Any
suggestions?

I have a terrible time convincing them, but the BEST solution I ever
installed was a nice Coleman 18000 Btu RV rooftop HEAT PUMP over the main
cabin hatch with the Coleman Easy Start Kit already installed. All the
noise from the AC, the noisy compressor, the noisy fan motor, the
condensate swamp water and everything except the small inside control
panel and distribution outlets fore and aft that stick down in the cabin
about 2 inches is OUTSIDE WHERE YOU'RE SLEEPING! Even the smallest RV
unit will make a boat MUCH colder, MUCH quicker than a "marine grade"
unit twice its capacity. You'll freeze your ass if you turn it wide
open...(c; The "Easy Start Kit", not available on "marine grade" units
I've ever seen, starts the compressor SLOWLY, without the 30A starting
surge current every time the compressor comes on. This allows you to run
the little rooftop unit with a PORTABLE or SMALL INBOARD generator! How
cool that is anchored up a creek on a hot, sweltering night full of
Florida mosquitoes the Manatees are afraid to surface under!

Look on top of the tugboats and trawlers! They use them because they
WORK.

The whole thing costs just a little more than the seawater pump in the
"marine grade" thing in the closet. So, when it finally rusts out...you
just BUY A WHOLE NEW ONE. It takes YEARS on a shrimp boat with NO
MAINTENANCE WHATSOEVER....

Somewhere near you is a motorhome/travel trailer superstore. They all have
them. Google search for "Coleman RV air conditioner" and find thousands.

I do find thousands of 110v AC's, but no 12 or 24v AC's.

Do you realize how many amps a 6000 btu air conditioner would require at
12 volts? Hey Larry, they don't just take heaters to the boat.

Yeah, but they're not smiling luggin' a 12V AC down the dock.

Hmm....My 8000 window unit in the computer room runs about 800 watts.....

800 watts divided by 14 volts (to be fairer) still equals a CONSTANT DRAIN
of over 57 amps!

Man, we're back trying to figure out where to stow these 3 ton submarine
cells, again, to run it all!....

Nope...A/C is NEVER gonna run off 12V!

"But you sold me a 4,000 watt inverter, didn't you?"......(c;

Hmm... 3 ton submarine cells. Too bad we couldn't
talk the manufacturers into making my 8500 lb keel
into one big lead acid battery ;-)

Call Electric Boat!

Phone: (860) 433-3000

They've got lots of experience with submarine battery banks....(c;

"Can we build one for you?"

I do realize how many amps, but I have a DC generator and don't want to
run the thing on an inverter.
