My neighbor had a new trailer that went in for slide work, when he got it back it had a hole in front of the entertainment center. The fix by the dealer was cut a big square and glue in a piece. Said neighbor having installed many a kitchen floor for HD refused the fix, wanting a whole new floor. After much hassle with both the dealer and the manufacturer he brought the trailer to the factory in Indiana, from Ma. For 3 days the trailer was gutted and a new floor was replaced along with the slide being removed and replaced which the dealer completely screwed up.
So the real fix for the floor is to replace it, after removing ALL the cabinetry etc. What's the chances of a dealer being able to do such? They'll probably want to piece it, which may look okay but probably will not stay that way.
