I decided on a high quality, 3/4" thick puzzle mat material from ProSource that has worked great. The formulation I purchased is very thermally stable with little expansion or contraction over the seasons. It is exceptionally lightweight, embarrassingly easy to install, looks great, impervious to water, easily cleaned (I can even remove a square at a time and hose it down, if needed) even replaceable piece by piece if damaged, and incredibly cheap, having spent less than $50 to do the entire trailer. It is available in a wide variety of colors, textures, even printed patterns. I installed an alternating checkerboard of dark gray and medium gray. It is extremely comfortable to walk on, and adds a bit of insulation from what might otherwise be a cold floor.
