2003 Chevrolet Silverado 2500HD 4dr Extended Cab LS Rwd SB (6.0L 8cyl 5M)
I traded my 94 K2500, 6.5 diesel for
the 8.1 vortex with the Allison tranny
and all I can say is wow!!. The Big
Dog Motor pulls my 5th wheel with no
effort at all especially when it comes
to climbing long......hills. Combined
with the Allison tranny, this is the
best power drive train that a RVer
could dream for save for the Duramax.
I get about 10.5 mpg when towing and
14 mpg when not which is not to bad
with 4.10 gearing. My wife likes the
quiet ride although it's little
stiffer than the old truck (new truck
has the camper package). The 03
exterior stying is Ok but a prefer the
Power, Power, Power
Need a bigger gas tank option for the
8.1. A 26 gal tank is too small. A 40
plus gal center mounted would do the
I Love, Love, Love this truck.. This is
the second truck I have owned from
chevrolet. I have never had a problem
with this truck other then routine
maintance. So this truck is a must
have for a person who is looking for
both power, reliability and Comfort.

This is a great all around truck. It's
good for hauling all the family,
friends AND all their junk - in
spacious comfort, unlike an SUV, where
you get room for people OR cargo.
Performance is incredible from 6.0L V8,
real-world gas mileage varies between
12 mpg city - 15 mpg hiway. VERY roomy
& comfortable. Very well built - NO
quality or reliability issues during
1st year of ownership.
Interior comfort, performance.
OEM 245/65/16 tires are too small. I
had to upgrade to larger tires but was
limited there, as the upgraded forged
aluminum wheels are also too narrow at
6.5". Needs a light under the hood. It
would also be nice if 2500HD had
optional variable ride control, offered
ONLY on 1500s.
these really are great trucks, and
they don't have to get awful mileage.
i am averaging 14.5 in town (i never
get on the highway) with the 6.0
liter, 5 speed and 4.10 rear end.
everything is stock, but am going to
add a K&N filter and bigger tires
soon. this is my 4th chevy PU in a
row and i had 225,000 on my last one.
nothing wrong with it, just got tired
of driving it.
