I can report my experience is that Thor Motor Coach (Damon is part of TMC) will sell you anything used in TMC RV's like the cabinetry and similar parts, for models being built at this time and a few leftovers from previous model years...that's about all that is available.
These sales will only be offered through a authorized retailer (no direct from the factory sales).
So, if the door sizes have been used on a TMC model in the recent past, it could be available. This starts with a call to TMC Customer Service : Customer Care | Thor Motor Coach #1 Brand of Motorhomes | Diesel Pushers,Class A,Class B,& Class C RV s
Other than that, cabinet repairs will require a local shop to repair/replace.
