This would make the most awesome tow vehicle out, there but i have no idea how much it can tow. I actually saw the quadski in person this weekend they had one in the front of the boatnrv.com showroom the down side is I believe these are both developments that where made for the military to use and they are just coming to the civilian side the quadski has a sticker price, maybe you should sit down.. Of $50,000.00 it was on sale this month at the place for$ 44,000.00  no idea what the trucks retail for but you have to check them out they are the coolest thing since fried rice! They would be totally awesome to take along on camping trips near the water.
