Our ‘C’ has AGM batteries for both house and chassis batteries so they self discharge more slowly than flooded batteries. Their 100% charge level is rated as any resting voltage >12.8V. I disconnect the negative connection from the chassis battery as the electric steps will slowly discharge the battery. The house batteries are disconnected via a disconnect switch near the entry steps that drives a relay.
Once a month I will take the motorhome out for a drive and also run the generator for an hour. Stabil keeps the gas in the tank fresh and reduces varnishing of the gas in the gen carb.
