I am building at Trolly top trailer. I am using Computer fans in the back of the trailer to keep the trailer cool or turn them around and draw moisture out. Some are from TV's the rest computers. one set will hang from a pole so I can flip them drawing air out.
I do some camping in Death Valley or southern California. So having a way to have hot air rise and be let out works best with a Trolley top trailer.
I am assuming I can run them on the usual 12 volt battery. Is there a better way to run them??
