We chose Allure Vinyl flooring for the trailer I wanted to get installed underneath as much of the cabinetry and furniture as I could. I had to get creative to support the toilet mount since I couldn't figure out how to remove the flange from the tank when I installed the subfloor. The vinyl flooring is a lot heavier than I expected it to be. I don't regret the decision but it's something you'll want to facto for. I'm not sure if pergo or other manufactured flooring is any lighter. The Allure flooring looks like it will hold up very well and looks very nice.
