I would recommend pulling both batteries and have them tested. The chassis battery should power the dash and every thing on that side of things. Just replaced the coach battery that showed 13 volts but would not even run the slide outs. As soon as the tester was applied it showed as failing. The chassis battery tested good but on the border of passing. Also follow the battery cables from the chassis battery and look for a solenoid or high amp rated fuse, fuse link or buss bar. Check all connections and terminals for dirt and corrosion and clean them.
