re flooring in your RV , we have a family cabin in the Sundre area , and have been looking at redoing the flooring , ( currently carpet and lino ) , but as always , costs play a part . Thoughts of new flooring are headed towards laminate flooring , but the cabin gets shut down in October and reopens in May , hence it freezes solid in the winter .
There seems to be a lot of different opinions about what can and can't take the freeze-thaw cycles . Vinyl ( floating floor ) seems to be the one that is least likely to work. Now others here before me say that its been just fine for them , so who really knows for sure. It seems that a glue down product would be fine ( lino in our kitchen/bath/entrance has been fine for thirty years.
Re laminate ( MDF core ) , I'm told ,by some , would absorb the moisture during the thaw and would swell , therefore doing damage , others figure that it shouldn't be a problem.
I do full Home Reno's for work , and as such have spoken to number companies that do these products and the general feeling is that most of these products " probably " would work , nobody will guarantee their product in this application . ( in the $ 3.00 a sq ft or less mark )
We could maybe go back to carpet , but it has added expense ( having to have an installer do it , vs laminate , I can do it no problem or we could even have several of the family members on it . So still at the drawing board .
So back to Your RV , I would think that you would be best to use a glue-down floor. This is assuming that your RV is outside during winter.
That's my 5 cents good luck with what ever way you go.
