Deja vu all over again, almost.
Yesterday I headed over to the storage lot to re-attach the remaining hardware (e.g. door handle, screen door catch, and trim bits). Visited the coach a few times to run the generator, charge batteries, and cool down the fridge. This morning I loaded up the Burb and headed to the coach. Couldn't open the door! Headed back to the house, picked up Chris and a stepladder, and attempted opening from the inside (after entering via a window). Turns out that the screen door latch was sufficiently out of adjustment to get hung up.
The last item I reattached yesterday was the fixed part of the screen door latch, the bit that's screwed to the entry door. With that in place, the two doors 'lock' to each other and, when the screen door got hung up, the entry door wouldn't move. Decided to just disable the screen door latch and get to it when we get home. Too much other stuff going on today.
