The amount of charge that most of our battery banks will accept is going to have only a negligible affect on fuel economy.

But since there is no free lunch here, you've got to get those electrons into the batteries somehow. Other than running solar when driving to charge your batteries, charging them from the tow vehicle is the only viable option. If you leave a campsite with depleted batteries and hope to have them charged upon arrival, then you pay the price to get them charge and take the ever-so-slight hit on MPG.
