solution to the hot van nights

Our solution to the hot van nights was to get a couple of brushless 4" 12dc fans from the surplus store. I mounted them on an 18" piece of house wire, then a big tough paper clip, and then light gauge wire to a 12v plug. The clip hooks to a shoulder belt anchor near the roof, and the heavy wire allows the fan to be positioned where required. The two fans are almost silent,draw only 75ma each, and I run them off a 35ahr auxiliary battery. (along with the tunes, DVD, and lights) I have yet to hook up the solar panel, as I have not yet to run out of juice during an outing. This may not be enough for southern extreme heat, but I was amazed how much better we slept. Our 3 way portable fridge was a great investment. (propane,12v,120v)
