Carl - I suppose at this point - it would not be funny if I asked you to post pictures and provide the year and model of the RV? No...not funny.

I watched a couple of Scwhintek videos and the motor needs to come up and out from the inside right? However the exterior keeper screw is engaged on the motor and will not let it pop up. You suspect the motor is probably toast anyway. Might be time for some semi-destructive techniques. What if you try to get a crow bar underneath the motor on the inside and see if you can overcome/bend/break the outer screw lifting the motor up so that you can remove it? See pic.
