If you connect the two HARD. then if you do something stupid (And you will, we all do) like leave the headlights on.. You are... In trouble.
So there is a device called a "Trick-L-Start" 3 wire hookup at the battery isolator solenoid.. one lead to HOUSE. one to MAIN. and ground.
IF the house batteries are charging/charged. it will "Connect" the chassis to keep it charged as well.. IF NOT or if the voltage drops below some point.. it Isolates.. So you still have power in one of the batteries you can use to crank up Mr. Onan's contribution to your RV (or whatever generator you have).
