I used Rock Tamers on my Cummins. I liked the looks better than the hairy looking tow tector thing. When I bought my 2011 F250, it came with a 2.5″ receiver so I cannot use the Rock Tamers as it will not slide on the new receiver. It sits in the garage now. I have had people that want to buy it but all out of state and shipping costs to much. Anyways, it was a good setup.
