I have kicked this idea around quite a bit. One thought which I havent done is the rocket box(on roof) drying rack. Set some type of rack inside to lay suit over. Here's the committing part. Drill vent holes in the front and rear and a drainhole in bottom of box. Drive around while wetsuit cooks dry. Or just park and it will still cook. I usually just hang my suit on a hanger in back of my transit medium roof with a plastic bucket under.
