We are interested in changing our carpet to laminate or tile as well so have just begun some research into the best choices, cost, weight, longevity, etc.
I understand they make special laminate and tile flooring for RV's, but I don't know much about either other than the tile is lighter weight. I'm not sure if the tile may be a better choice for you because of your heat issue. If so, are you able to use the tile from a big box store or does it have to be made special for Rv's?
