There were some odd shaped air mattresses used for a few years. Some were 10" thick at the head and 24-30" thick at the foot of the mattress. They, like most "cheap" air mattresses began to leak after a night or two. Keystone installed "120 VAC automatic pumps" to compensate for the leaks, the pumps would run as needed to keep the mattress filled. Problem is that when dry camping, there is no 120 VAC, so that plan "died on the vine" and Keystone has pretty much stopped installing anything but commercially available air mattresses.

If what you need is one of the "odd shaped ones" then expect to spend a lot of money on a mattress that probably will need replacement at least annually. I would suggest looking for alternatives or a new sofa/sleeper that doesn't need the air mattress. If it's a commercially available size (don't think that WalMart or Target will have all available sizes) from a major air mattress source, I'd buy a better quality and not look back.

The reason Keystone and other manufacturers used the air mattress concept was to save storage space when the bed was not being used. Converting back to a foam slab (folding or not) will present a major storage issue when the bed is not in use, so for most RV'ers, converting to foam is not an option.
