Hi Bailey,
I have thought about this topic a lot. Several years ago I purchased the mattress topper from GoWesty. It definitely made a difference, sleep wise, just giving a little more cushion on what was already a pretty old and tired mattress which was kind of skinny from the beginning. I don't think you will have trouble closing the roof with the topper, at least I didn't in my '95 EVC. I do want to comment, though, on Darin's post. I think that constructing an entire new mattress (there are some really good options for purchasing foam - here's one:?) is a really smart idea. For one thing consider that your existing mattress is at least 20 years old and for another, who knows what quality WInnebago put into it in the first place? I have been a little bit (really just a little) annoyed at having "one extra thing" which, in this case, is the mattress topper to stow and worry about. Darin's idea does away with this problem. Maybe you could fit an upgraded mattress into the supplied mattress coverings? That would save some expense. Or you could do what I have done and just enjoy the little extra cushion that the topper provides.
Hope this helps,
