We have had (sheet) Forbo Marmoleum down in our '64 GlobeTrotter for 8+ years and are so happy with it we have installed it in our '56 Safari. The GT has over 25,000 miles on it (and the Safari about 700
). We haven't had any problems with telegraphing seams, we made sure our floors were very solid and the linoleum was professionally installed.
Cameron is right, it is a natural product that doesn't bode well with standing water though...
One other thing...you will have a seam, Marmoleum is not wide enough to go wall-to-wall without one. That is the main reason we had it installed professionally, they "weld" the seam for a flawless finish. Now if you are using the term "linoleum" generically when you actually mean "sheet vinyl" (which is an entirely different animal) that's a different story. It can be found in wider sheets and installed wall to wall. I have no personal experience with sheet vinyl in a trailer, but wouldn't recommend it either. Many are made in layers that will come apart with the trailer movement which is unavoidable.
