Well thats the thing. I'm not looking to make it 65 degrees on a hot day, just looking to go from like 85 to 77 at night, just to make it sleepable.
I just ran the calcs at an online BTU calculator, and thats actually 211 BTU/hr, for my 45 cubic foot v-berth with a change of 8 degrees F.
So it might
work?? Maybe I could just get a fan to put over top of the portable DC fridge?
