I just ordered a double towel rack that attaches via suction cups. The offset from the wall would be about 6 inches. If it actually st icks well, then I plan to attach it somewhere on the fridge side of the trailer ( experimenting with location) and just hang a lightweight towel type material from it. Maybe even wet it to generate cooler air. Might take a while...the towel rack is coming from china. The top, bottom and sides would be open allowing air flow. We'll see how it works...probably can't hurt!
