One of my friends just picked up a new Peterbilt long nose conventional with a 600 hp Caterpillar and an 18 speed transmission. The thing cost $132,000.00 and has a 255" wheelbase. Huge 24.5" polished aluminum wheels and so many other things I can't recall. Oh yes, it has a gps, fridge, microwave and a satellite tv in the sleeper compartment.
I took a short test ride in it since I have a CDL. Boy that thing sure does sound good with a deep diesel clatter and well over 2,000 lb. ft. of torque.
