I would call Tiffin and give them your work order on the first go around and see what they have to say and if that does not work try and get ahold of Bod Tiffin. They have repaired stuff way after the warranty has run out. That is one thing good about Tiffin but you would think after all the same repairs year after year they would change something and get it right.
