Great camper truck

Vehicle: 2006 GMC Sierra 2500HD

I purchased my GMC 2500HD SLT 4x4 with the 6.0 engine and locking rear differential to haul my new 8.5 foot slide-in camper. I picked the camper up at the factory and proceeded on a 4500 mile test run. Encountering heavy cross winds in the Dakotas and steep passes in the Rockies had little or no effect on the draiveability of the truck or it's performance. The camper weighs 2370 pounds dry and yet the truck responded with little difference than with an empty bed! Mileage on the way to the camper factory in the midwest ran between 14-16,at speed limit empty and 11-14 with the camper loaded.

This is my first GMC truck and so far I'm pretty happy with it. I have to say though I got what I expected from a 3/4 ton truck. Pulls the loaded dump trailer with ease. Fuel economy is rather dismal but it is a full size pick up with a 6.0L V8 so what can you expect. My power steering pump "whines" which the dealer tell's me that its just the way a 2500HD is. That is the one thing that bothers me the most about the truck.

I had an '04 2500 HD and liked it enough that I traded it for an '06 equipped the same. The employee discount was the reason for the switch. It does have a stiff ride, but then, it is a HD instead of a softer pulling 1500. I can pull my 3,000 lb steel horse trailer with 2 horses with an average weight of 1,000 lbs each, and I do not know it is behind the truck. No matter what type of terrain or road condition, as long as it isn't ice covered. We havn't had snow or ice so I havn't had a chance to put it to the real test as yet, other than pulling the horse trailer.

I have owned 7 GMC/Chevy Trucks over the last 25 years. This truck measures up to the others very well. The only real complaint I have about it is the fact that that it is very light in the rear end. I am a disabled veteran and need to be able to move around in the cab quite a bit in order to stay comfortable and find that this truck gives me the freedom to do so very easily. Riding in friends trucks has shown me that I certainly made the correct decision when I chose this vehicle.

What's New for 2007

Reborn for 2007, the GMC Sierra 2500HD boasts major improvements in build quality and cabin refinement as well as increased towing and hauling capacities.

Introduction

Better late than never. Finally tiring of criticism about its pickup trucks' spotty build quality and Fisher-Price-grade cabin materials, GMC gets a major clue for 2007, and the result is the fully redesigned GMC Sierra 2500HD full-size heavy-duty pickup truck.

The outgoing generation of the Sierra 2500HD (which is still available under the "Classic" nameplate) was a strong and sturdy workhorse, but the Achilles heel in that truck was its low-buck interior ambience. This year's full redesign yields improvements that are immediately apparent upon climbing in. Materials are higher in quality (less hard plastic than before) and panel gaps are tight and even. The styling is more cohesive as well and overall the new Sierra's interior, especially in top SLT trim with its lustrous wood and metallic accents, is attractive and comfortable.

Outside, the styling is aggressive, and GMC's designers have made an attempt to differentiate the truck's look from its Chevy Silverado twin more so than in years past. The muscular hood hints at the power underneath, and indeed the revamped engine lineup boasts higher output ratings. The standard engine in GMC's 3/4-ton pickup is a 6.0-liter V8 with 353 horsepower and 373 pound-feet of torque, while optional is the brawny "Duramax" turbodiesel V8 that makes 365 hp and 660 lb-ft of torque. Newly standard is a six-speed automatic transmission (for either engine) whose extra gears promise better performance and fuel economy when compared to last year's four-speed unit. Combined with the truck's new, stronger frame, the Duramax powertrain allows impressive payload and towing capacities of 3,458 and 13,000 pounds, respectively.

With its strong work abilities and well-rounded personality, the 2007 GMC Sierra 2500HD is a solid pick in the heavy-duty pickup truck segment. We already favored last year's GM heavy-duty trucks over the Ford F-150, so it stands to reason that the new GMC will stand ever taller. But if for some reason you don't find it to your liking, you might also want to consider the Dodge Ram 2500, which offers nearly equal towing ability and ride comfort but lags behind in payload capacity and optional bed configurations.

Body Styles, Trim Levels, and Options

The 2007 GMC Sierra 2500HD is a 3/4-ton full-size pickup. There are three body styles available: standard cab, extended cab and crew cab. Standard cabs are fitted with a long bed. Extended cabs and crew cabs can have either a standard or long bed. Regular cabs can be had in base Work or midlevel SLE trims, while extended and crew cabs can also be had in plush SLT form.

The Work trim comes with the basics, including air-conditioning (extended and crew cab versions), a trip computer, OnStar telematics, vinyl seating, a 40/20/40-split front bench seat and a tilt steering wheel. The SLE trim actually consists of two subsets: SLE1 and SLE2. The SLE1 adds deep-tinted windows, chrome grille trim, foglamps, alloy wheels, a CD player, cruise control, full power accessories, cloth seating, keyless entry, an auto-dimming rearview mirror and a leather-wrapped steering wheel.

Step up to the SLE2 (in extended and crew cabs) and you'll get dual-zone automatic climate control, six-way power front bucket seats and steering-wheel-mounted audio controls. The top-of-the-line SLT adds leather seating, rain-sensing wipers (with heated washer fluid), a Bose audio system with six-disc CD changer, keyless entry/start, an exclusive dash design with wood/metallic accents, 12-way power and heated front seats, rear audio controls and a Homelink universal remote.

Available options include XM Satellite Radio, remote starting, a power-sliding rear window, a navigation system, a rear-seat DVD entertainment system, rear park assist, a sunroof, the Z71 Off-Road Package (skid plates, off-road suspension and locking rear differential), the Safety Package (power-adjustable pedals and park assist), a snow plow prep package and a cargo management system (which includes sliding tie-down hooks in the front and sides of bed interior).

Powertrains and Performance

Standard on all Sierra 2500HD trims is a 6.0-liter V8 that puts out 353 hp and 373 lb-ft of torque. It's matched to a six-speed automatic transmission. The burly Duramax 6.6-liter turbodiesel V8, which boasts 365 hp and 660 lb-ft, is optional and comes matched to a heavy-duty Allison six-speed automatic. Properly equipped, the 2007 GMC Sierra 2500HD can haul up to 3,458 pounds and tow up to 13,000 pounds, making it equal or better than other competing 2500-series trucks in both areas. Buyers have a choice of either rear- or four-wheel drive. The Work trim with 4WD has a traditional floor-mounted selector for the transfer case. All other 4WD trims have Autotrac, which features an automatic setting that shifts into 4WD when wheel slippage is detected.

Safety

Antilock disc brakes and a tire-pressure monitor are standard. Stability control and side curtain airbags are not available. The optional Safety Package includes power-adjustable pedals and rear park assist.

Interior Design and Special Features

The fit and finish of the new Sierra 2500HD's cabin is vastly improved compared to the previous generation. Exacting build quality as well as attractive materials and simple controls make it easy to get comfortable inside the big pickup. A one-touch, three-blink lane-change feature, plenty of storage cubbies, three power points (including one in the console box) and well-placed cupholders add to the user-friendly environment. The luxurious Sierra SLT features a unique dash and door panel design with handsome wood grain and metallic accents, giving this workhorse the feel of a premium luxury sedan.

Driving Impressions

Based on our experience with the new Sierra 1500, we expect the redesigned 2007 GMC Sierra 2500HD to provide sprightly performance, especially with the diesel-fueled V8. On long trips, the 2500HD's supple suspension should swallow bumps (even with the heavy-duty towing option) while still allowing confident, no-slop handling with a minimum of body sway through the turns. The cabin is impressively quiet, making long trips all the more enjoyable.
