by overhaul on Sep 26, 2009 Vehicle: 2003 Chevrolet Silverado 2500HD 4dr Extended Cab LS Rwd SB (6.0L 8cyl 5M)
I just bought this truck about a month ago. Only problem was a bad serpentine belt. The power is very nice. I have the 6.0L and I can't feel any weight that I haul - It's like its not there. I used to have a 94 Chevy Cheyenne with a 305, and anytime that I put even just passengers in it, it felt lugged. I love the interior - feels like I am sitting in a recliner in a living room. I average about 10mpg when I am not towing, but hey, its an HD. Love the 3000lbs+ payload. It's very cozy on the highway.

I love this truck! The 6.0 litre is powerful and smooth. With a locking differential and 4.10 gears this baby hooks for a 2wd. The one big complaint is bad MPG I average 12 to 13 no matter how I drive it; city or hwy. As far as its intended purpose it huals everything I want with no effort! Including, but not limited to cornering at 60-65 with a big heavy trailer and tractor very little sway and with the HD trans and cooler it never gets over 160 degrees with a load. Interior very spacious and well laid out. The suspension is tight and rides a little rough with no load but who cares its a HD.

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
The Silverado 2500HD now sports a new front fascia and revised side moldings and taillights. Top-of-the-line models also get power-folding heated mirrors with puddle lamps and turn signal indicators. On the inside, the Silverado offers numerous entertainment options including a Bose stereo system (with rear-seat controls on crew cab models), XM Satellite Radio and a rear-passenger DVD-based entertainment system (crew cab models only). The instrument panel and center console have been redesigned, and Chevrolet has added new seats, a more comprehensive driver information center and a dual-zone climate control system. On the hardware side, the standard 6.0-liter V8 gets electronic throttle control, as well as the ability to run exclusively on compressed natural gas (CNG) or a mix of CNG and gasoline.
