The Burb weighs in a little more than the truck.
Also if you have just a 1/2 ton truck regular cab short bed, which is around
119 wheelbase.
That makes a difference to, especially in ride comfort.
The wheel base on the 1/2 ton Burb is around 136 inches.
I myself prefer 4X4's for the extra weight up front, plus getting in/out of
some places.
