Robert, this may not help much, but there is a drawing at:

Trust me when I say removing the assembly isn't easy (I've done it) but it is doable. Everything is done laying under the coach - with the genset door open, you can access the headlight adjustment cable, and see the attacment hardware.
Once during a trip, I had the misfortune to hit a turkey, dislodging the entire assembly. I removed the headlamp assembly in order to "glue" the mounting hardware back into place, and then reinstall the headlamp assembly.
