When I found a white screw on my folding steps I had no idea how it could have gotten there. A quick search located the empty hole at the top of my door.
Our 2010 8526RLWS has an air shock at the top of the door which at first look is a life saver on a windy day. It has prevented the door from flying off in a stiff breeze. We have learned to be very careful opening the door since the piston is very powerful and will yank the door out of your hand when it gets about an inch open.
Thus my issue. When I examined the door piston the brackets on the wall were very loose and of the three holding the door bracket on, one was on the step, the middle one was loose, and the third one was stripped out at the factory and caulked in place. The bracket on the frame was held in with very short screws that only hit the aluminum door trim and were too short to engage the trailer wall framing.
Not only that, but the closer yanks on the door so hard that it has pulled the top away from the hinges so the door no longer is vertical to the frame (it hits the top left corner and sags at the lower left corner).
I repaired the closer brackets by drilling completely through the door and installed 2 inch #10-32 SS Bolts held in place with nylon insert nuts and a SS washer. The frame bracket was repaired by removing the short screws and replacing them with 2 inch screws that actually engage the trailer wall frame.
Since the hinges are "pop" riveted to the door, I am still pondering what to do about that. Trying to bend the hinges does not work as the wall flexes.
