Haven't asked for or received a check, but I've receive major repairs, including labor, long after warranty and I'm a second owner too. That was from American Coach and the item in question was a entire new hydraulic jack system. They readily agreed the original system was inadequate and invited me to bring it to Decatur to have it replaced. No hassle at all.
