2015 HC 343RL front room slide problems

[Pmatt]

2015 HC 343RL 5th wheel with kitchen table/front room slide problems.
We bought this trailer brand new, at about one year in we were on vacation and I noticed something hanging from under the slide, taking a closer look I noticed that the barrier under the slide was all torn up and hanging down. Took the trailer into dealer when we got back from vacation, and after a couple of weeks they let me know that Keystone told them that it was not a factory defect and was not going to warranty it. The dealer ended up removing the slide and supposed to have fixed it, also keystone did pay to have the carpet replaced. Since then the slide has been removed a fixed a total of 5 times now with no resolve. The trailer is back in again and now they are not going to cover it at all, it is all up to me. This has been very upsetting 3 years with the service and resolve both from Keystone and the dealer. I have been RVing since 1986 and this is by far the worse trailer I have ever owned.
Has anybody experience anything like this?
And any help would be appreciated.
