The door zipper is little hard to close. Not too big of a deal. If you don't put the straps on the front corners too tight it works a little better. None of the tension straps that hold the tent to the truck need to be very tight anyway.
I did not get the air mattress from them. I found a nice queen size one from Costco with a rechargeable pump for $30 and it has worked well. The bed of the truck is little hard if you don't have something under there.
The floor of the tent only has 3 small straps at the front of the tent, back of the truck, that attach between the tailgate and bed of the truck. Realtruck.com confirmed my order quickly and shipped it out the next day, good service. One other benefit is that it will fit behind the seat when all packed up, just like they say. Good luck.
