The entry door opens perpendicular to the body of the motorhome and can not bend back toward the motorhome. When the wind or breeze comes by, it moves the door back and forth. I am concerned the air will bend the hinges on the door. What can I use to keep any damage from the wind/breeze? The body of the motorhome is "smooth", nothing sticking out to attach a rod or bungee cord. How would I attach a rod to the body of the motorhome? Some kind of hook?
