[KAYE RIVERCITY]

....are you using OSB on the bottom of the deck?....coat that with a serious layer of undercoating or some thing waterproof--it will swell and degrade after being wet ONLY 5 times......UNLESS YOU ARE USEING THE NEW OSB WITH THE WATERPROOF GLUE-URETHANE I BELIEVE THEN IT IS- WARRANTED FOR 50 YEARS. I got a piece in a bucket outside all winter about 4 inches wide and about 16 inches long....soaking in water and ice from September IIRC....still a board not a wet pulp!....Floor is important to keep flat and dry at all times.......there is no way to repair unless you do a rip out-which I did on my first Airstream trailer.....what a bitch it was to do but I got it done and replaced with the Urethane OSB.....about $50 a sheet here now for 3/4".....geofkaye
