You know it is kinda sad...
My cousin has an 07 4 door cummins dually and he put mud flaps...
Measured 5 inches above the ground, bolted them on.
A few weeks later he hooked up his gooseneck cattle rack and loaded about 10 cows and 4-5 calves in it. Calves were in front and cows staioned over the tandem axles.
Went about 20 miles to the county fair and wore almost 3 inches off of his mud flaps...
