How to install strut, chain or strap to cargo door without it?

[tnedator]

I have a Thor ACE. The cargo doors have nothing to prevent them from swinging all the way open and either getting in the way of the entrance door or swinging into the latches on the other door and being scratched.

I'm trying to find some struts, chains or even nylon straps to prevent the doors from over opening.

Has anyone done this? What did you use?

I do have some nylon web strapping, but before trying that, I wanted to see if anyone else has addressed a similar problem.
