Gonefishin put the interlocking foam tiles in for his flooring. It seems to be holding up well. It looks great, and they really like it. See about page 6 in his build. viewtopic.php?f=42&t=33924&start=75
Lots of ways to address the issue.
I added 2" of pink foam under the trailer attached directly to the ply floor; with the foam glue and 2.5" screws with fender washers; I haven't put may miles on it but its been insulated for 7 yrs now and parked at high elevation in the mountains and used extensively in cold -15 to -20C sometimes over a winter weekend and I was surprised at what a huge difference it made; added this after a very cold October weekend in 2010. I put the glue on the foam then used a small jack with 2x4 and ply to press it in place while glue dried; you need to buy the special "foam rated glue". Happy warm trailering. cheers bc dave
