When we bought our current camper it had the original 2002 inner spring RV mattress on the storage box. The mattress was probably miserable when new but after all the time it was in there became a torture device. I gave it away before trying to sleep on it and headed down to Billy Bob's Beds in San Antonio and bought a full size queen which was almost 3 times thicker (pillow top) than the original. The pillow top matches the one we use nightly in our stick and brick bedroom. I put a piece of plywood across the end of the storage box under the mattress so there is no sag. Access around the bed is a tad more limited (was poor to begin with in a low height 5th wheel) so we just jump onto the bed from the end. The mattress sleeps like the one in our house and is one of the best modifications we have done out of many.
