Bob,
    Thanks for the info. I presume the solar panel would be a charger for the batteries. I'd be very interested in the results because I'm seriousoly thinking of that too. Presently I have the standard aux battery under the driver seat but it seems to drain pretty quickly. I'm not very electrically minded so it'll be an adventure.
