FB,
That was a great idea! I should try to find some smaller tires and wheels so the speed is a bit slower. I also need to clean up the dock, move the eyes out to the ends of the dock, and I will drill directly to the top of the dock instead of my temp blocks. And fasten the winch motor down. Probably move the motor to one end of the dock.
Here is the ride along in the barge test video.

Thanks a bunch for all the suggestions and brain power!
