If it is due to the owner not keeping the unit sealed, there is no warranty.
If it is the factory's fault, it has been reported that they will even repair one outside of the normal 2-year warranty window.
What is happening with your unit, and what model/year do you have?
I would think they should cover you, as you aren't that far out of warranty, and considering they already worked on it.
Are you sure the "curve" in the wall is delamination, and not some other, maybe more serious, problem?
Why did they replace the roof?
I don't think that is totally uncommon. The walls are so shiney that any imperfection shows up like a sore thumb.
If you cannot push the 'curve' in, then it is probably not delaminated.
Just out of curiosity, how does the roof delaminate? Did the plywood just under the roof skin come loose?
Hey I am glad I saw your thread. We have a 2012 Surveyor 235RKS that apparently has roof delam. I have only had it for 3 months, camped in it once so far. The roof vents had a recall because the calking they used did stick. Took it to the dealer and they replaced the vents and also told me when they inspected they found the roof was delaminating in the front left corner which was causing the EPDM, Alpha systems roof to be pulled up and lifting the caulking away.
Very dissapointed and feel that a new trailer should not have this problem. I very much want to get a refund or a brand new trailer but think that is a far stretch from what FR will want to do. how did you handle it?
How is it worthless? The OP was asking about warranty on wall structures. Photos are needed to answer that?
I believe the warranty on the wall structure would be one year, unless you got an extended warranty
