tractor supply has a set that each holds 1000lbs each so you have 2000lb load weight over both of them. They have a arched center. like a bow it allows the cart to go up and over without dragging. They have a strap that you hook to bumper to keep them from falling or moving. they are not cheap. but neither is a GC.They are right at 8 feet long too. When I used them to load my cart in my LB truck before 5er they fit under the CG in the bed and they took the length of the bed to store them. Just in case they did not fold in half either.
