Has anyone had to tackle replacing the floor of the raised sleeping area of a 19' fifth wheel? I just brought home a (new to us) Scamp, and discovered in the journey home that the front window leak was substantially worse than it originally appeared. The OSB is soaked through.
Looking at the outside and seams, I did not see any obvious points where the plywood is fastened to the steel floor supports, or to the fiberglass shell. I'm assuming the plywood is bonded to the shell.
I did not see any write ups on this - just the raised "dance floor" dinette in the back. Any tips or advice is appreciated!
What year S-19 do you have? Two or three windows in the upper deck? First fix the leaks and dry out the floor. The upper floors are attached with counter sunk screws down the center of the frame rails. I also thought they were screwed to the angle pieces under the deck. Do you have screws showing through the angle iron under the top deck? The wood is attached to the sidewalls with fiberglass tabbing on top and below the floor.
Next evaluate your floor, is it just wet , rotted or stick your finger through the floor rotten. I have seen some good scamp OSB sub-floors that if you poured a cup of water on them water it would run through them to the ground. If the floor is dried out and not rotted too bad you can make them solid with a products like Get Rot and save a lot of work . If you use these products you will have to first seal the underside so the Get Rot stays in the wood and not runs on the ground. The floor in the upper deck usually does not carry that much weight ( less than half ) and is usually better braced than in the back/side walls. I would be more comfortable doing these types of repair vs.total floor replacement in the upper deck. (Pictures would help in evaluation of your floor.)

Trailer is 1991 vintage (I need to confirm with the VIN later, but that's what the paperwork said). It has three windows - the leaker is the front window, in the usual spot. The water damage is under the two side windows - mostly on the left hand side, due to how the trailer was sitting. Wood is damp through, but only deflects in one small spot when pushed with a finger. The OSB has a fiberglass skin on the underside that is mostly intact, but that's hindering drainage right now. Hopefully it helps with the Get Rot!

From what I can see from the picture you should be able to deal with what you have and not have to replace any of the floor area
Front window repair: I found it best to just pay the price and get the window seal and lock strip from Scamp. I mark the bottom center of the opening. Then start laying in the seal 1/4 to3/8" past the centerline mark. I use a rubber mallet to seat the seal onto the fiberglass. When you get to your start point cut the seal about 1/4 " past the mark, make sure the the seal ends are cut square. Dry fit and force the ends together with the rubber mallet. Once you ensure you can get the seal to seat squarely, pull the ends apart and and apply black RTV (silicone) or windshield sealant and re install the seal. Then you are ready to install your window. If you have a solid rear widow with a rubber seal you might want to check that seal.
Once your deck wood is really dry and repaired I would seal and or paint your upper deck. Once the wood floors in a Scamp get wet they tend to give off a slightly funky odor even when they are dry out.
Good luck
