The 2002 HD Sierra with the 8.1 V-8 and
the Allison transmission is tremendous!
I think there is so much hype over the
Duramax, the 8.1 gets overlooked.
Unless you drive 30,000 miles a year or
expect to keep the truck forever the
$4,000 premium for the diesel doesn't
make sense. Properly equiped, both tow
the same. But it's that big block 496
cube engine that puts a smile on my
face everytime I start it up. My wife
loves driving it too! I'm sure I could
get better mileage, but I can't keep my
foot out of it. I get about 12 MPG.

The 5 speed Allison transmission.
