Don't know but the doors on our TT are made by this company. Maybe you could contact them.
Challenger DoorIf it's a hinge or even the complete door you'll need, you may find the manufacturer's name on the back of a door, otherwise your TT manufacturer can tell you. Or the parts dept. at a dealer may be able to help.
I just came across this company and they show the hinge for the door as separate pieces. In white and 16' lengths only tho. I see that they call it a "belt rail" hinge.
