Hi,
My husband and I own a flooring store. My husband specializes in installing new flooring in RV's but when installing LVT (luxury vinyl tile) we only use the top quality Freefit Products which is what the well known Lazyday's RV'S uses.
We also carry another loose lay product called Surefit by Natures Choice, if you want a floor that is going to last than I highly recommend either of these products, Freefit is available in wood look planks with a smooth or sculpted design or 18x18 tiles 2 of which look like Travertine tile, they also have a carpet look tile as well, Surefit is available in wood look planks only. Unlike laminate or the box store kind that has to be either glued or clicked together Freefit or Surefit is entirely loose laid, no glue or clicking and the planks or tiles can easily be replaced if damaged, you also have easier access to any storage just by picking up the plank.
Metroflor's Konecto is another brand that is also just as good but is not a loose lay, both Freefit, Surefit and Konecto are only sold by local dealers.
Just remember to do your research on box store brands and the problems they may have when choosing your flooring!
Happy RV'ING!
