Another option would be to look for a local RV Salvage Dealer. Last year
, on my Long, Long Trip, I found a RV Dealer who also bought damaged units (as trades for new) and sold
the parts off of the damaged units. I needed a hatch door for an exterior storage compartment. Got one off a smashed 5th wheel, and took the tail lights
too; which I put on the share table at Bullard's.
Old Mobile Homes are another source of these parts.
