Top of door opening during travel

Our little turn-button that holds the top of the door closed when towing didn't seem to be doing the job. It wasn't turning, but it just wasn't long enough. I finally solved this problem by making a longer one. Taking a hint from the plastic thing that holds the halves of the door together, I cut a piece of plastic from a commercial electrical box cover plate. I then cut off the original turn-button to use as a spacer and screwed the two pieces back in the original hole. I also found that you should always turn the contraption clockwise or the screw may loosen. (The same as with the original turn-button) I have a picture if I can figure out how to attach it!
