We keep our TM (Elkmont) in a storag lot with no power or water. And we can't bring it home to charge the battery or fill with water (14 story condo) on a cul-de-sac. So we had a solar panel 80 watt installed when we ordered it. We do not dry camp and the batterys always have a good charge and I'm able to mess around fixing stuff at night in storage.
