I had similar thoughts recently when I realized that, with a certain amount of effort, I could get my summer average to 40 MPG.
My idea is a two position alternator switch. Position 1 would be "normal". Position 2 would shut off the alternator. The truck would continue to run off the standard battery. A second deep cycle battery would charge the standard battery through a DC-DC converter with about 14 volt output. The second battery would be charged from a flexible solar panel mounted on my topper and charge controller. I would want the deep cycle battery to be sized for four hours at 20 amps into the standard battery. The solar panel should fully recharge the deep cycle battery in 8 to 12 hours.
I don't think I'll ever do it, but it's a great thought experiment.
