I just got this truck last month but so far, I am very impressed. This is my 7th truck and my first Dodoge. It is roomy, comfortable and although stiff, I like the ride. (It feels solid like a truck should) Off road in low 4wd, it is a hoss. On the highway in 2wd, it drives very well and is very quiet.
Laramie model has all the bells and whistles. Very comfortable for the whole family.
Not real sure about the multi displacement engine. Although very smooth, I can tell when the engine cuts back to 4 cylinders. I wish it had an over-ride for folks like me who drive very little and are not that concerned about the gas mileage.
