Dutch 12078; I had not pulled the window out but, it's out now; there was a thin 1/8"x 1/2" rubber gasket around the window and in the corners it was hardly in contact with the fiberglass, the guy at our local RV shop had never seen this type of gasket. I got a roll of regular window sealant tape, I will put it back in tomorrow. Just don't have the stamina I did.
Richard: I don't know where a toggle bolt may be located?
DrewE: I have replace all the clearance lights with new ones and new gaskets. but that does not mean one is not leaking. I will re-pull them out and recheck, maybe recaulk the holes where the wires and screws go through.
I have also rechecked my ceiling and I don't see any stains or feel anything wet.
