2005 Dodge 3/4 ton 4x4 with ATS modded Cummins. Pushing about 550 hp and around 800 ft-lbs torque. I could have more but it hauls my 9,000 lb trailer at the posted speed limit all the way up I-70 and still gives me 17+ mpg average overall while staying under temp red-line at full throttle. Next planned mod is the ATS intake manifold and water injection.
