Don't forget, different frame, axles, wheels ( 8 bolt ) and dual tanks... 8.1 is not known for excellent fuel economy...Airwolf said:Officially, the 2500 is a Z85. Major differences are leaf springs in the 2500 vs. coil springs in 1500, different transmissions, and of course, 8.1 liters of raw power in the 2500 baby!!
zukracer said:I think you'd also want to consider that Z71 gets you bilstein shocks and a full skid plate package that won't be on a 2500. I've driven both on road and they are close in ride, not sure about off roading but I will say the skid plates are very nice to have if you drive off road.
If you need/want the power, get the 2500 but you'll pay for it at the pump, just ask anyone that has one
