Thanks for the suggestions,
I would be shocked to learn that jacking could distort a structure as strong and ridgid as a fiberglass 'egg' particularly in the area of the reinforced door frame.
The issue seems to be with the aluminum hinges. (Once the screen door begins to rub on the frame, the screen hinges bend a bit more and more each time you open the main door, which of course takes the screen door along with it, unless you remove the plastic latch.)
When the problem first occurred in Big Sur CA, I had to unscrew the screen and remove it just so I could get in and out of my trailer!
Since the hinges are riveted to the door frame, they must be adjusted in place. When I returned home, I was able to use some 'bending' tools to improve the situation. It no longer catches in the upper left corner, but now it rubs at the lower left corner, and on the 'lock plate.' but I'll bet there is a factory protocol for getting it right.
I am eager for the folks at Casita
in Rice to return from vacation.
That said, they certainly deserve some days off, we are buying their products as fast as they can make em'
All the best to all who contributed!
