we got the solar fan at camping world. it shows you where to mount it and has a really long cord for the solar panel which is about 3in by 5in.
also put one of those cube fans in the fridge that run off two d batteries. we live in s. az and it seems to help alot
Cool (literally!). What diameter is the fan and did the package have any technical info like how many cfm the fan moves? I called the manufacturer, "Valterra" here in Cali, and the gal told me it only moves something like 1.2cfm as compared to their other two 12v versions that move 12.5cfm.
