I recall an engineer in the lunch room at the Duramax factory, telling me to get rid of my 6.5td, a D/A combo would pull anything I had, better, up steeper hills/grades etc......yeah right!
Bought one a few years later.......Stalled the dmax on a STEEP grade the 6.5td went up with a 12K trailer in tow! yeah right says the engineer who helped design this motor! Turns out the dmax had less gradibility than my 5 sp 6.5! On a freeway grade, yes the 300+hp left the 185hp rig on the side of the road! More to towing prowess than just HP and Torque!
