I camp in my Brenderup - just got back from camping this weekend. I pull the center bar out, drag out the matts, wash out the trailer and let it dry. I put a little window unit in the groom door and use duct tape to secure a plastic garbage bag above it to seal the door. I have cots (don't like them to sleep on!) and then I put an air mattress down with blankets. It is more than cool in there (I live in Texas - it is HOT here!) and very comfortable.
I would like to par down what I take though because packing and unpacking it bites!
