Well the wife and I have endured the factory mattress for too long. I have been “given permission” to remedy the problem. After much research I think I have more questions than when I started. I have decided to keep the short queen size. No topper, we are replacing the whole mattress. I have narrowed my choices down to two, but am not settled because I just don’t know. Mattress Insider Luxury Mattress and Wilderness RV Montana Hybrid Mattress. I have also considered Dynasty, Zinus, Lucid, and a few others. I have concerns where people report mold after use on memory foam, seems like no breathing under the mattress because of the solid base. Sleeping hot is a big no go, which the gel supposedly fixes. The Hybrid I just don’t know anything about in general, but looks promising. I have a select comfort at home, but don’t really like or hate it and do not want one in the trailer. There also doesn’t seem to be a whole lot of talk about the Hybrid either. Anyone have experience with any of this or suggestions?
