35QBA: How thick can replacement floor be?

[Sweet Ethel]

Hello fellow Tiffin lovers!
I’m new to the RV world as of a year ago. I have a 2012 35QBA and love it! I’m having the flooring replaced and need help determining what thickness of flooring I can use without impacting the slides. My existing floor is vinyl tile, guessing ~2mm.
I live in southern CA so no extreme cold weather. My unit has 4 slides although not sure if all are on rollers, at least one is. Looking for a durable replacement option that isn’t so thick it’ll screw up the slide operation. I’ve been looking at LVT and LVP but open to suggestions.
Has anyone replaced flooring in this or similar rigs? What did you use? How thick can I safely go?
Thank you in advance!

TIP: Regardless of flooring, more important is design/ condition of the ROLLER SYSTEM, SO I would start there? The BEST floor cannot survive a bad, seized, or broken roller.

Thank you for the tip THenne1713. As of today all rollers and slides are in great shape and not causing damage as is. We will also be sure all are clean and no screws or gravel have found their way into spots that might cause damage before we lay the new floor.

Would love to have an update here on your progress for this new floor. My wife would like to do this and it worries me to no end! Let me know what you find.

@Cdubbs,
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!). (https://www.lowes.com/pd/Style-Selec...l-Tile/3386290).

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!
