Duramax/Alison 2500HD 4x4
By john_bud on


2003 Chevrolet Silverado 2500HD 4dr Extended Cab LS 4WD SB (6.0L 8cyl 5M)


The 2500HD is head and shoulders above
the 1500 in capabilities. Towing is
much improved with the 6.6 diesel as is
fuel economy unloaded (currently at 18.3
mpg all unloaded, I track all fuel use,
miles and hours). Build quality has
improved, with a better "feel" to the
interior. The information center has
been replaced with a truely informative
data center. You can track all vehicle
use, business vehicle use and personal
vehicle use, by selecting options.

Diesel sound is noticable but in no way
objectionable. From the inside, you
can't tell it's a diesel.

Best Features

Drive train, the duramax is the best diesel engine out there today. Power Fold-in mirrors are great for those off road trips where the road is too close to the trees.

Worst Features

Include boost guage and exhaust pyrometer. Add more maintenance reminders to the vehicle data center
