I uses a fan that I got from Amazon that's battery operated ( 4 -"c" battery) and hang it right inside the rear slider with the slider opened, than I just opened the rest of the windows around the truck about a 1/4 way down just to keep the air flow moving for my dog on a hot day ( but he never be inside longer then 10-15 min. ). But then again, it don"t get that hot around the San Francisco Bay Area anyway. If it's too hot he won't be in the truck by himself at all. The battery will last a long time before I have to replace it and I alway have spare in the truck.
