What I tried one summer in my 4x4 was to run a sealed light on its own fan with a source of filtered outside air venting back outside.

I then used a second fan to keep the air negative pressure in the tent with passive intakes, sucking out through a carbon filter and venting into the room. A wall unit kept the room cool.
