I'll never own another 2WD again...What's this 2WD configuration you talk about? ...LOL
One would think there would not be any difference between the two. It possiblity could be an issue if it was a transmission tune but still highly unlikely. I do know the 4WD system has its own separate controller for dealing with the transfer case and front axle disconnect actuator.
My dad farms in a place that gets less than 10" of rain annually and is flat. Hardly anybody has a 4WD truck there. No sense paying for something you haven't needed in 50 years.I'll never understand why anyone would buy a 2wd truck. Trucks are supposed to be capable in all situations.
