Okay, maybe I have a bad case of the stupids. I tried to remove the dog house engine cover on our 2007 Sunrise W22. Our previous MH had the Allen wrench socket at the back and 2 screws up front. I can NOT find the Allen socket in the back on this MH. I've pealed the carpet up at the back several inches. I've been over everything with a magnet. I just don't see any openings for the wrench. If I lift the whole thing up along the sides I can feel that it is attached at the mid point in the back. I just don't see how.
