Thanks Restorium, "Tunes" or radio, I had hope that with the switch on, it took the radio from the engine battery to the house batteries but not sure. (Fear of killing the starting batteries)

And the Horn switch ... have tried the horn both ways - no differences.

But was wondering if they are in the on position and RV is off are they draining the starting batteries? (Again fear of killing them)

Thanks for the help...
