Thanks for the response Bumpy, I have calculated the weight of the tile,thinset and groute to be approximately 450 pounds and do not believe this to be a problem as it will spread over the entire length of the coach. Am I wrong? My concern was flex cracking.
If your concern is flex cracking, then you do not want to use thin-set. Thinset is a concrete type mix which is great for stick built homes but I would use a flexible acrylic tile adhesive as well as a flexible grout in a coach installation. I have seen tile installed using silicon as the grout which is certainly flexible and available in many colors.
When touring the Winny plant last year, I watched several crews laying tile with thinset. I doubt that the very large tile that is currently popular would do well in a thin layer of adhesive. Modified thinset BTW, is stunningly flexible. I once built a stove mat of 2" tiles over a layer of 1/2 Hardie board. This assembly sat on a berber rug with padding under. The whole assembly was flexible enough that you could feel it give and rebound as you stepped on the edge, much like a stiff rubber mat. In several years of use there were a few cracked grout lines, but the tile held tight.
