My wife and I just put down an inexpensive laminate, covering the main floor in our 2010 28RKBS. We removed the carpet which revealed vinyl and we put the new floor over the vinyl. Looks great. Has not buckled or changed in any way that I can tell and we just finished a 4500 mile trip after installation. It completely changed the appearance of the inside of the 5th wheel. Tearing out the carpet and installing the new floor took about 4-5 hours. We bought our floor at a local store in St Louis Co, Mo called Hoods. It is not touched by the slide as it goes in or out. The stuff we put in is not quite as thick as Pergo or as heavy in weight. The few cuts we had to make were not too difficult and it is trimmed with matching quarter round.
