I'm looking at building a sleeping platform for my suburban for warm weather camping. Id like to have a fan, but don't want to cut the roof to install a vent/fan. Has anyone made a fan in a panel that would fit in passenger window? removable, and would plug into 12V wiring? Also, if you leave the windows and barn doors open, has anyone made any mosquito netting that would keep critters out? I'm thinking something with magnets to keep the netting in place. don't want to permanently modify the suburban.... if anyone has pictures they would be great....TIA.
