Battery & electrical questions
I have a 2014 Coachmen 21QB on a Chevy 4500 chassis, with an Onan 4KW generator. *Does the generator have its own starting battery? If so, how is this battery charged? Or does the generator crank...

Before I moved to AGM I did get 70 amps of charging. Now that doesn't happen at all which is why I've invested in a dc to DC charger. My bank is fairly large and I use it LOTS.
My OEM wire for charging is a #8 and would blow the OEM 60 amp fuse. These are hard to find. I doubled up on the #8 with a second charging path fed by the chassis battery and used twin automatic reset breakers rated at 50 amps.
I used twin solenoids rated at 200 amps contacting and have manual control of their charging.
When the battery bank was full, I'd use the excess energy to run the electric water heater. I would monitor the chassis battery voltage and shut down water heating when it displayed 12.3 volts.
I'm hoping to have 7.2 kwh of usable storage after the summer.
