I have a vinyl floor material problem. The last threads on the subject of replacing a vinyl floor that I saw in the forum go back to 2016. I'm trying to source a material to replace the vinyl floor material installed by Keystone. It is pulling away from the walls, is not laying down on the floor well, and just looks old, like me. There are also a couple of screw heads that have worked their way through the present material.

Is there a newer flooring material that works well for RV's that I should consider for my DIY replacement project? Our 5th Wheel will experience temperatures below freezing and way above being hot (in excess of 115F during summer months while in storage). I'm drawn to vinyl planking but the literature on the stuff I have looked at state that the planks are not recommended for use in RV's.
