You got to remember alot of guys like dont use their trucks like trucks like V V and it is just a grocery getterit would be pointless. You realize these trucks are made for towing? Another overdrive with a load would never be used. You would not have enough torque to do anything in a double overdrive with a load.
I don't know about you, but i dont have a load 100% of the time. And going down the highway it would be sweet to have.
