Has anyone used indoor/outdoor carpet squares in a coach? This looks like a possible good solution to replace old carpet because it could be replaced in small sections if needed. I have no carpet experience and wonder if the squares could be made to go over flooring ledges.

I used them for this application back in the 70s (shag)
Worked quite well. Only got about 5 years of use.I don't see too much consumer level (big box) available these days. There are some really good commercial squares out there. (banks, airports, etc)
