Paul,
I know that there was a period of time with issues of tile cracking and grout that could not tolerate the flexing and travel rigors of RVs. When I visited the Beaver factory I asked and it was discussed, but I cannot remember the materials that they went to, that for the most part solved the problems. Not sure if what is left of Monaco would have that information, you could try. BCS would more than likely provide information on what they use.
There are vinyl tiles now and vinyl wood flooring that are quite convincing. Seems that would eliminate any cracking question if you found what you liked in that material.
