Thanks guys. 
Knoll, I get good ventilation through the two windows.  At 2 am when I crawl into the camper it's cooled off.  The insulation should help keep the daytime heat down.
I finished installing the insulation today.  I had some left over so I added a 3rd layer to almost all of the ceiling.  When I was done with that I started on the flooring.  That went pretty quick.  It makes it look a lot better inside.

New floor mat installed

I put the temporary shelves back up.  I need to come up with an idea for a permanent setup.

I got a memory foam mattress for it.  No more noisy and uncomfortable air mattress.  The box said it might take 48 hours to fully expand.  The mattress is a little larger than the bed platform.  I'll wedge it in there once it takes shape.
