Anyone with 12v Air Conditioning Experience?
Having spent the better part of a week in a hot, dry and smokey campground that doesn't allow generators to run (I posted previously about this issue in another thread) it got me to thinking about som...

To add to the discussion, I found this chart that gives an estimate of the BTUs needed to cool a particular square footage. Looks like ~5000 BTUs is enough to cool 150 square feet which is about what a truck camper is I think.
The Dometic Coolair 1000RTX provides 4,094 BTUs so I think it would be a bit undersized for the job. The RTX 2000 however looks like a better contender with 6,824 BTUs of cooling capacity. I know in my original post a mentioned the RTX 3000 but in light of this information, it seems overkill. I also didn't realize there was an RTX 2000 until someone mentioned it earlier in this thread.
During this summers smoke and heat I put a 5000btu window unit temporarily in my BF's kitchen sliding window. To cool the camper from 98 inside and 100+ outside it took a couple of hrs to get the camper into the low 80's. Once cool the AC started cycling and it was comfortable at about 78.. The bed area was really slow to cool off at the head of the bed. I have a nice 12vdc fan that I was able to position to make the cool air get into the bed area.
The AC pulls about 4 amps in cooling mode compressor running.
