Not too long ago I bought a 1990 coachmen classic 310mb and since day one the side entrance door has been sticking bad enough that I have to use a putty knife to open it. The PO left receipts that had a technician note about attempting adjustments on the door but was unsuccessful so I imagine it may have been caused by damage to the stairs throwing the door out of square. Here are some pictures that show what it looked like prior to this evening before I tore the steps out MH Door - Imgur
You can see that the left side collapsed and they installed a metal bracket to try to hold it up... unsuccessfully.
Using a level it appears that the door is leaning to the left ( \\ ) but is catching on the entire left side, especially near the middle. There is some water damage to the wall to the right that may have something to do with it but I'm really unsure.
I'm mostly lost right now, and any help would be greatly appreciated, I'm rushing to get this working in time for plans this saturday.
