" 3. The front-most dining table seat (over the generator) is screwed down. Beneath it is a large completely empty compartment, with no way to access it, (other than by unscrewing the top cover). Is there any reason why I shouldn't remove the screws and make use of this large compartment?"
Are you sure it's empty? That is where the fresh water tank is located on our coach.
"1. In the cab, just above the mirror adjustment switch is an unmarked switch that, when pushed, illuminates a red light beside it???? What does this do?"
That should be the on-off switch for the heated mirrors.
