Water leak damage
Sorry to see your leaking issue. It seems the Mfg's. are not interested in quality or durability! I had major structural failure to my dinette slids floor. I just got it back in with a new floor. Mine was a poor seal design along the top edge of the exterior trim. Mgf says no, my fault for not maintaining this small edge bead of sealant. When I took off the exterior trim there was no sealant on the verticle edge, only along the horizontal edge that was screwed to the floor bottom. No where for the water to go but into the wood floor. This much damage in 1-1/2 years of ownership.
