I am going to run a dually rear. I have been bouncing the idea around often since last July when I bought the truck. I am fully confident that after I complete the suspension build and the wheels being machined properly, my decision to stay with the dually rear will be a great one. I want the stability of the dually. I am going to the E-rating tires probably in the summer. I have 8 of the MT's and I have had friends who have never had issues with them. I see it as a hit and miss. Some say they are horrible tires but i disagree if you know anything about wheelin them!
