Diesel is wonderful
By E. Daniel Shoemaker on


2004 GMC Sierra 2500HD 4dr Crew Cab SLT 4WD LB (6.0L 8cyl 4A)


Traded in my 96' GMC 3/4 ton Suburban, w/ 454
Vortec engine for this new crew cab, Duramax w/
Allison transmission. Wow what a difference in
towing power. Previously driving over mountins into
Prescott and Payson, from the Phoenix area, we
were lucky to keep up 35mph. Now, wow, 65mph
over the same roads and mountains, towing the
same trailer. Diesel milage is better than the gas by
about 5 to 6 mpg. Wish the Suburban had this

Best Features

All good. Love the controls on the steering wheel.

Worst Features

Add in GPS. Could really use it for work. $47,000 truck ought to have one ... don't you think?
