Thanks for posting this Dan,I never even thought about this before your post, but along the same line if you have the Trimark outer door latch I found it is less wear on the inside latch if you don't slam the door shut but pull the handle out then push the door shut. The inside latch is just a zinc alloy and prone to breakage. I replaced mine twice and when it broke the third time I took it apart and fixed the broken latch with a steel plate. I was not about to buy another one at $100 a piece. Some on this forum carry an extra one just in case of breakage.
