Has anyone ever done any kind of insulation on their camper shell? We drive to Az a few times each summer and the dogs ride in the back. I'm going to get the windows on the shell tinted to help keep the sun out, but I was thinking about insulating the shell itself as well. It's just thin fiberglass so I would imagine anything would help. I was thinking of using the Lizardskin ceramic insulation. I know there's only so much that can be done, but I figure every little bit helps.
