Work truck z82 priceless

Vehicle: 2007 GMC Sierra 2500HD Work Truck 4dr Extended Cab LB (6.0L 8cyl 6A)

Best truck for the buck. 98% of this truck life has been pulling a 3.5ton trailer on the hills of western PA. Its like an old hound dog ready to work. Its powerful and comfortable for the wife and kids. Handles like a long Camaro. I get about 18.8mpg @ 72mph and about 13 combined when towing. Rented a diesel but it has too much torque for stop & go. Get props every time I stop for its true work look. Only 2 problems, TPMS and an exhaust gasket failed.

Vehicle: 2007 GMC Sierra 2500HD Work Truck 4dr Extended Cab 4WD LB (6.0L 8cyl 6A)

In "07 I needed a truck to tow a 7000lb 14x9x9 box trailer in western PA. I test drove 'em all and fell in love with a Ford until I learned GM had the most torque, hp & mpg. Found a GMC L82 with all towing packages. I tow 5 days a week and avg 9.5mpg city and 15 on the hwy at 62mph or 2k rpm, above 65 mph the aero drag zaps the mileage to 10.5. The PA hills takes another mpg. Without my trailer I get 15 city and 21.5 hwy. I love the performance and the bucket style seats, it feels like a Camaro on steroids. Get compliments every where I go and with 30K miles I've been everywhere.

Vehicle: 2007 GMC Sierra 2500HD Work Truck 4dr Extended Cab SB (6.0L 8cyl 6A)

Bought the 6.0ltr WT version two weeks before leaving Maryland. Installed cruise control and hauled 5500 lbs on a 16ft tandem trailer and 1000 lbs in the bed. Averaged 16mpg on Hwy after tuning with the Diablo Predator using 87 octane gas. I have the 4:10 HD posi-lock rear. I average 12-13 mph in town. I would have liked the 6spd Allison transmission.




My first diesel

Vehicle: 2007 GMC Sierra 2500HD SLE2 4dr Extended Cab SB (6.0L 8cyl 6A)

I never had a diesel before but my prior experience with gas trucks was tainted with getting 13-15 mpg. So I opted for the diesel with the allison. Wow. I get 19mpg average and on highway trips I average 21.5. I put about 31000 on it so far in 10 months of ownership and I have no complaints. The true genius of this whole setup is the transmission. In tow/haul mode it downshifts for you when you brake while matching revs. Really saves the brakes and instills total confidence in pulling heavy loads - skid steers, tractors, trailers full of blocks, etc. I get about 15-16mpg while towing on the highway. Great truck!

Vehicle: 2007 GMC Sierra 2500HD SLE1 4dr Extended Cab 4WD SB (6.0L 8cyl 6A)

I purchased my GMC a few weeks ago so far so good. I had a Ford F-350 powerstroke with 7.3. The GMC is small in the inside compared to the Ford. The GMC has a lot better fuel mileage but seems to be too light to handle heavy trailers. It's not short of power it will smoke my Ford easily. My biggest complaint is lack of interior room. GM still needs to do their homework on that. The quality is not matched by Ford or Dodge in the interior and standard accessories, but I think Ford is heavier duty than GM for all out abuse on the farm or on construction sites. In about a year i can tell the truth because I know Ford can hold up. Curious to see if GMC can.

Vehicle: 2007 GMC Sierra 2500HD SLT 4dr Extended Cab 4WD SB (6.0L 8cyl 6A)

This truck is by far the best combination of utility, comfort, and performance I have experienced. I love the truck and highly recommend it to anyone in the market for a new pickup.



Full 2007 GMC Sierra 2500HD Review

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.
