Sorry for the first entry. Here is the real post.
When we traded our 2014 Classic for our new 2018 Classic we acquired a new problem. The entry door will not close properly. The dealer's answer was to "slam it" Not true. The door is/was not adjusted properly. Specifically the frame bolt it mounted to high so it hits the door latch wrong. The result is it was necessary to slam it to close it.
At this years International ever coach in the dealers display along with every coach on my dealers lot had the same problem. The bolt is mounted to high.
There is a You Tube video that describes how to adjust the entry door.
Or you can print this 14 page instruction from Airstream on how to adjust the door. Attached.
