Slide floor construction

[Nomadicchefs]

After having located and repaired a leak in the slide roof that caused the slide floor to soften, I have found multiple threads pertaining to the construction of the floor. They all seem to state that the slide has more than 1 layer of osb with a thin layer of "insulation" between them. However, now that we are finishing the repairs to the floor, I have noticed a really stupid mistake on Keystones part - the furniture was all attached to the floor with wood screws, but they used screws so long that they went clear through the floor and the darco. It wasn't until we removed all the furniture that we understood why the slide kept "catching" when moving it. My question is, how many layers is my slide floor supposed to be? Because as far as I can tell (from the lifted edge of darco) the slide floor is seriously maybe 1/2" thick. All this time I've been trying to figure why the floor sags the full length of the slide, it must be all the moisture getting in where the screws went completely through the wood.
