Need to haul a 1,300lbs bull moose off the Alaskan tundra? You're going to need an Argo. The world's only eight-wheel-drive, amphibious ATV can literally go anywhere.
Witness the idiocy of these crazy Russian kids being towed in sleds at really high speeds. Make sure to watch the entire video, because it really gets nuts. How fast are they going? 60mph? More? I don't know, but for sure it's way too much.
This is a tow rope wound around a center pin, for easy windup. It's rated for 3333 pounds. Not sure I like this thing that much. Some simple designs—a tow rope—shouldn't be messed with. Just learn to wrap your ropes like a sailor. You don't want to be dealing with knotted equipment when emergencies come up.
