Don- To my knowledge the truck battery (more importantly the terminals for its alternator) are within jumper cable distance. Is that, along with trickle charging in the morning, a viable solution?
John- Pawnee is in front of winch truck and retrieve car. So while technically they are “put away” I do not see this as more of a problem than it would be during the flying season. Just move the tow plane out, get the stuff and move it back in. Am I missing something? Has the configuration changed since I was out last?
