When you say "if the subfloor can handle it" are you referring to the
weight of real hardwood? If so, the weight will not be an issue at all--
even a very small person standing on the floor will put far more
pounds/square foot than hardwood flooring. In fact, some mobilehome
floors are not that sturdy-- kind of "springy" feeling. Real hardwood
(about 3/4" oak) would actually be better than laminate I would think.
Good luck Larry
