I don't have solar. In addition I store my Vegas at the Navy Supply Depot in Mechanicsburg PA. Their Auto Hobby Shop has an empty Hangar and they store RVs and trailers in there. The Hangar has a water deluge fire suppression system so they keep the Hangar at about 38 tp 40 degrees during the winter so that the fire suppression system doesn't freeze.
The two knife switch disconnects will allow me to totally isolate the house batteries and the chassis battery. I'll still go over about every 2 months, close the knife switches, check the battery voltages, and run the generator.
