Opened her up and found the main backset slide plate had fractured at the two weakest points (see arrows).
Luckily my local RV guy had one in good shape (less the inside trim/handle ass) and he parted with it for a song. (I chose In'a godda' Davida' and he made me dance through the entire 19 min drum solo). After I adjusted the position of the striker/catch plate on the door frame, she closes like new again. | 
Driver's door lock/latch calved on me. Worked okay from the outside but no go trying to open from inside. | | |
