On the passenger side outside just to the left of the coach entrance door there is a black plastic thing that is about 2.5" wide and 4" tall. It has the letters M7 on it any ideas what it is?
I just installed another one of these "black plastic things" and a tilt/swivel arm in the bedroom to easily move a tv from one location to another. They also have a trash bag holder and table that attach to this same blck assembly.
