Had a 2003 2500 SLT 5.9 turbo diesel 21 mpg and went with the 2500 Laramie 6.7 diesel 16 mpg not to good for a diesel, be nice to have the shifter button on the steering wheel also with the exhaust brake. Overall the truck is very quiet. Laramie package is a must! Dodge make better cup holders. Improve fuel economy.
