We have used the air mattress alot in our tent camping days. When they came out with the folding bed with air mattress pouch really solved the sleeping on the the ground thing always associated with Tent camping. We always carried two of the twin bed size with us and tied the two twin bed frame together with tie wraps.
The biggest thing we had to deal with was the changing of the outside air pressure during the night from being nice and firm when going to bed in the late evening and then waking up in the morning completely sunk down inside the Air Mattress...
You can see out two twin bed setup in the lower right hand side of this photo. Sure is nice sleeping off the tent floor...
I always had to re-pressure again around 4-5AM each morning...
I don't remember ever going over the specified air pressure...
