I full time in my '06 Dynasty while working in the RV industry. I had the same issue with the OEM Comfort Aire mattress which is two independent adjustable air chambers. One night it I woke up and the bladder on my side was fully inflated at the head of the bed, nothing at the foot so that was the end of that mattress. I tried the Casper/Purple/Tuft&Needle technology..what a disaster. Them mattress' are too heavy for the bed slide gear and are too big for the platform and I couldn't close my slides. So...I did a search for custom Gel Foam mattress' that compete with the name brand bed in box products. Low and behold, Amazon has a mattress vendor that is 100% Amish made to order, healthy material mattress for RVs called Travel Happy. I called the number on the product listing and the guy who makes the mattress answered the call! Brilliant! I bought the 12" Graphite Gel Foam premium mattress...best sleeping decision I've ever made. Granted I am 5'7 142 lbs and sleep on my back mostly, with a little bit of flipping to my stomach. Hope this helps!
