Be sure to do this soon.... I don't have pictures, but one day I closed my door behind me (on the way in) and the spring loaded latch snapped in half leaving absolutely no way to exit through the door. 4 hours later and many trips through the window, I had cut through the TriMark lock and was able to pull the spring out and retract the latch.
Also, here is a link to where I purchased the replacement.
Save at RV Partscenter - RV Parts and Supply
Checking with local RV dealers, they were charging anywhere from $125 to $250 for this. This link shows it for $63.
