Mine is a Cummins 6.7L, w/ 6sp A/T
but I couldn't find that as an option on the drop down menu.
I love this truck. It's big and sits up high, but doesn't drive or feel unwealdy. Fit's nicely in the lane and tracks down the road. Ride is a little bouncy, but for a heavy duty truck, is the best I've ever ridden in.
The interior is simple but nice and well thought out.
I'm currently getting around 16MPG mixed city/highway, which is pretty good for a truck of this size.
I got the truck for work, not for a commuter, but I enjoy driving it so much, I look for an excuse to take the truck.
Solid feel, good build quality.
Awesome Cummins sound
No stupid Diesel Exhaust Fluid
Drives nice for a HD truck
Fuel economy could be better, but isn't bad for the size vehicle it is.
