My refrigerator door would once in awhile pop open on rough roads , you wouldn't know till you stopped to set up. We boondock a lot so we see more rough roads then most. Did not like the bungee idea , so here is what I did. Drilled small hole through top plate into door , made a small L shaped pin that I insert into hole while traveling. I have a small rubber plug I put into the hole in the door when pin not in use, so as to not compromise any insulation factors of the door. Minimal as it might be.
