Geeze...LR makes and has researched the exact hitch system that works for the truck. Why is everyone bothering to remake the system when the one supplied works perfectly with the truck. By perfectly I do not mean without difficulty of taking the tow hitch on and off the truck. I leave mine on 100% of the time and then the only problem is solved.
LR factory hitch setup is commonly referred to as "the plow". Well earned reputation if you have every towed on a forest service road.
