hello I did my RV floor 2 years ago with vinyl flooring tiles that click together. everything looked good the first summer, that fall I put the RV away for storage and as I live in Canada the temperature drops to minus 30 during winter. The tiles shrink so much during the cold that they brake the interlocking edges crack and even though they do expand again in the summer after two winters I will now be replacing the flooring with something else. So be careful about the expansion issues due to temp. changes. I am interested to hear from others what flooring tiles they have put down that did not have this issue
