After realizing I wasn’t going to be able to upgrade to what I wanted without a very expensive install bill I went back to peel and stick tile and had a local guy do it. I’d not recommend this route generally but for us this works for now. I actually love the loon of the tile I picked but also know I’ll have to replace them here and there (I bought lots of extras!).

To do it right with material I want I’d need to take out the bed and potentially adjust rollers which means taking it in to a shop since my RV is not stored at our home where we could have time and freedom to DIY.
If you do opt to redo the floor we found removal of the old peel and stick easy except under slides and bed. There are actually a few old pieces still under there at the moment. There was a lot of old sticky adhesive underneath that should be removed first with adhesive remover, then be sure the floor is clean before adding whatever primer you need for the new floor. Our installer didn’t do a great job with this unfortunately. Lesson learned!
FYI there are a few thin commercial grade vinyl
options out there that would work for you without risking a height change. One brand was Flooret I believe. floorcity.com had quite a few and I could search on thickness, type, mil (wear) rating, etc.
I’m sure that’s more info than you wanted.
Best of luck on your search!
