2015 Villagio 25tbs - unknown switch

[jwnall]

My new-used 2015 Villagio 25tbs has a rocker switch which is just to the right of the steering column in the 2014 Mercedes Sprinter 3500 chassis. On the top of the switch it says "chassis" and on the bottom of the switch it says "coach." Any idea what this switch does?

A picture would help, but just by your description it's to toggle between the house batteries & your engine battery.

My Bounder had the same switch, but labeled PARK / TRAVL for powering the dash radio/CD player/display. When travelling, I'd set to TRAVL so the power for the radio would come from the engine battery - which was kept charged by the alternator. When we got to our campsite or when boondocking, I'd set to PARK so the power for the radio would come from the house batteries - this way the engine battery wouldn't get run down while at a campsite.
