would like to find a good air mattress to sleep in the back of the 80. Limited space cuz of the big fridge. It should preferably be 24", at the most 30" wide. I mean the thick ones you inflate with a compressor, not skinny self-inflating backpacking types. The few I've seen online -mostly intended for camping apparently- seem to be pretty low quality, thin material, and not likely to last long in a rough environment (as in sleeping on top of boxes etc). Anybody knows of a good sturdy one?
