Keeping wind from breaking door hardware?

Who has come up with a good door stop idea for RVs with a slide behind the door so the door cannot open 180 degrees and use the standard "open door hook"? Our Winnebago has a gas cylinder but strong winds can easily grab the door out of your hand breaking the pretty flimsy gas cylinder parts. I was thinking of the old "chain and spring" like you used to see on wooden screen doors of the past but the screen door on the RV gets in the way of attaching it to the main door. Any ideas?
