looking at flooring at big box stores, the allure and other vinyl interlocking flooring looks like a good idea...... Until I picked up a box of it. That stuff is HEAVY. way heavier than sheet vinyl. So..... my first concern would be how much cargo carrying capacity are you using up using it for flooring vs. sheet vinyl. and is that an issue for you.
and then there is the std disclaimers. for use between 55F and 85F and not for use in sunrooms, RV's etc. many have had success in trailers, while many have run into issues with it with temp changes.
