12 volt air conditioners

Interesting idea ModelA29. As someone that used to make my career in the HVAC/R field, and before that in the automotive repair business, just consider that is a long run for the refrigerant. Ducting to the front may be interesting considering condensation, and flow loss of such a small system. I'm not nit-picking, just saying it's an interesting idea. I'd say #8 automotive wire going back there would be a good idea (Jegs).

Do us a favor, and take some pictures after you are done.
