I am interested in the purchast of a new ram 2500 4x4 325/610. The dealer was telling me on the phone that he had one 2005 6 speed left with a button on the dash board to engage 4x4. My question to you guys is "is there a nutral position on that button like a floor 4x4 lever?" Hi 2x4,Hi 4x4, nutral, and Low 4x4. I think nutral would be an important feature for the use of a PTO right. Is that button a good reliable way to engage 4x4? In advance thanks.
