A ramp and block and tackle to aid in laoding deer and bear and hogs and other animals in the truck on solo hunts
A "Comealong" would make much quicker work of hauling stuff into your truck bed than does that stringy/pully thingy.
That "stringy pull along thingy" is called a block and tackle BTW.
I disagree... you can leave a block & tackle anchored in front and run it without crawling into the box to use a ratchet hoist.
I clicked on the video expecting to see the stupid animal loading trick of pulling the animal on board by tieing the one end of the line to a tree and pulling away...
