Fleetwood MHs from 1999 on charge both house and chassis batteries when on shore power, gen, or when the engine is running. I cannot speak for other brands. Fleetwood kept all the electrical systems the same for supply parts, and construction purposes, not to mention repair work. Not everything you read on this form is factual, or true. It takes at least a 40 watt solar panel to charge the house and chassis batteries. Most have a 10 watt or less panel for the chassis battery to maintain it. If it is low, it will maintain it low, not charge it back to life. A charger with at least 1.5 amp output is required, and will take at least 24 hours to return it to starting condition.
