2003 Chevrolet Silverado 2500HD 4dr Crew Cab LS 4WD SB (6.0L 8cyl 5M)
The Duramax diesel/ Allison tranny
combo is great. I'm getting 19-20 not
towing & 12-13 pulling a 9500 lb
trailer. The Duramax gives me power to
spare. The diesel is the best thing out
of GM in years. The ride is not bad
considering the tow rating, which is
better than Ford or Dodge.
