You would think the caulking would be covered but it's not covered at all. The factory doesn't even warrenty it while it's on the dealer lot. The dealer is responsible for the caulking while it's on the lot waiting to be sold. This is what I was told. If a new trailer suffers water damage while on the lot and it's determined to be the caulk at fault the dealer will have to pay for the repair. Again this is what I am told by the dealer.
It does seem like a very high quality caulk. I think the warping is what caused my issue. I suspect if it hadn't warped it would have held for a long time.
My trailer is at a storage lot a long ways from home (HOA won't allow it at the house
) but if I make it up there I will snap some pictures.
