Long Answer: A warranty of any kind is only as good as the company issuing it. If you are unfamiliar with the kind of quality that RV companies build, you need to read some more.
Short Answer: no.
Qualified Answer: maybe, depending on who sold it to you. On our first TT (incidentally a Rockwood also) I had an electrical issue shortly after warranty expired (factory had OBVIOUSLY installed breaker in a very unsafe manner). My local independent small dealer fixed it without question and apologized for my trouble. So, again, it depends on the rep/honesty of who you are dealing with.
