Swung the clamp around to clear the dually flare. May not be quite as sturdy.
But had a tussle unbolting it. The lock nuts that came with the system were not the nylon insert type, but a type that deformed the treads of the bolt making them virtually unremovable. After an hour of trying, finally had to hacksaw the bolt. If you install this, throw away the 3/8" SS nuts and get some regular lock nuts from a hardware store.
