Ted, did the Griswolds ever borrow your wagon? Gil
I think he was a Ford guy. A friend assures me Jesus was a Ford guy, too-he went everywhere barefoot because his shoes wore out from walking, because the Ford would never run!
Worth noting, the wagons work best at boat launches when they have the limited slip rear differential. Mine all did, but a friend had one with an open rear end, and it spent more time stuck at various places then mine did.
I think the little motor, above, is called a "Mud Bug" specifically for duck boats and what-not. They will run in really shallow water.
Best,
Ted
