When your house battery is near dead, your 12 volt DC appliance controls on fridge etc. may not work and your generator won't start unless you have the truck engine running and charging your batteries.
This happened to us on a recent trip .... the house batteries were just a bit too far down to turn over the generator in our Class C. I just went up into the cab and held the battery boost switch in the ON position while the DW hit the generator start button back in the coach and the generator started right up.
The battery boost switch in a motorhome can be used both ways -> by holding this switch ON the coach batteries can boost the engine starting battery or the engine starting battery can boost the coach battery(ies) -> so as to start up the built-in generator to then charge the coach batteries. This is an advantage that a motorhome RV has over a towable RV.
