For my '13 3100...
There is an electric access panel to something (not sure what) in the stepper door area on the left as you go in.
There is a fuse panel (for the coach stuff) in the bed base on the passenger side.
I went out and started digging. The panel at the entrance is the control panel (fuses and breakers) for the coach batteries. I found the main panel in the base for the bed and when I looked I found one of the 15 Amp breakers was tripped. This is a 2014 2860 and I had to take it in to have the generator fuel pump replaced (1.2 hours of run time on the gen) and I don't know if they forgot to reset the breaker after service or if something tripped the breaker. I am going to monitor the situation and see what happens.
The good news is that the 12V bus is in the same panel and it appears as thopugh there are 5 or 6 empty slots for additional assecories (e.g. a macerator pump hookup).
Thanks to all for the replies.
