Hey Jason
Unfortunatly we have not seen or found any 12volt air conditioners that would really work in any sort of practical situation.
They will draw TOO much power and will suck the batteries down in no time at all.
I think for example, one of those 12V AC units posted . . . <"48 amps at 12 volts ">> would kill your camper batteries in less than 4 hours.
Most deep cycle batteries have an amp hour rating of approx. 75 - 100 amp hours per battery.
<< 337lbs of deep cycle batteries >> . . . this would probably be 6 or 7 deep cycle batteries. :O The solar panel will never be able to keep up with that.
It seems like customers that get an actual air conditioner unit (not a swamp cooler) will be running the camper air conditioner on 110/120V shore power electricity or will have the camper plugged in to a generator when running the air conditioner. On a tiny air conditioner you might be able to get away running a 1000 watt generator, but most air conditioners will like a 2000 watt generator a bit better.
We can install a "rear wall air conditioner" in the Keystone Model ($ 700.00), but when we do this you will be loosing the inside shower connections. The small cabinet & inside shower water connections won't fit in the camper if we install the rear wall air conditioner on the Keystone Model. You would need a generator or 110/120V shore power when running this air conditioner.
(see attached sample picture of a camper that was on the production line awhile back)
We just installed a roof mounted TurboCool "swamp cooler" for a customer a couple of months ago.
It was the first one that I know of that we have installed at the factory so I don't have any feedback yet on how well it is going to work. After the next few months we will have some customer feedback to be able to report on if it was "good" or "bad" for actual cooling.
Even though it was a 12v swamp cooler, it seemed like it was drawing quite a bit of 12v power. When we turned it on in the shop, you could see the interior camper lights dim a bit.
Hope this helps.
