With three cab sizes and two box variations, the 2008 GMC Sierra 2500HD 2WD can fulfill any driver's needs. However, along with this huge truck comes a huge price tag. For the smallest and least equipped trim, the Sierra 2500HD is base priced at $28,535. Nevertheless, you'll be happy to know that the 2008 Sierra was voted Best Expected Resale Value by the Automotive Leasing Guide and was also awarded Consumers' Most Wanted Large Truck by Edmunds in 2007, beating out formidable foes like the Dodge Ram with ease.

The Sierra 2500HD can either have a Vortec 6.0L SFI V8 or Duramax 6.6L Turbo Diesel V8 mounted under the hood. The Vortec can produce up to 353 horsepower, while the Duramax can reach 365 horsepower. Both are excellent options for a heavy duty truck. A 6-speed automatic is standard on all trims, but the transmission can be upgraded to an Allison 1000 6-speed automatic also. An off-road suspension package is available on the SLE1, SLE2, and SLT trims. However, the Work Truck trim is not available with the off-road option.

GMC has given its Sierra 2500HD 2WD a massive payload of up to 3,892-lb. The 4WD version can reach up to 3,646-lb. The Regular Cab Long Box 2WD with the Vortec engine gets a whopping 10,400-lb towing capacity. But watch out for the Sierra 2500HDs equipped with the Duramax engine, they can pull an even higher 13,000-lb. All trims feature an external transmission fluid cooler too.

Just by looking at the Sierra 2500HD a consumer can tell that this is a tough and rugged truck. Chrome front and rear bumpers add a bit of bling to the otherwise dull exterior of a heavy-duty truck. Also, a chrome-surrounded grille graces the front end. Either 16" or 17" wheels are available. Buyers get a choice of either painted steel, chrome-styled steel, shiny forged aluminum, or even machined aluminum. All the trims also come with a steel spare tire.

Unfortunately, GMC does not provide estimated miles per gallon for the 2008 Sierra 2500HD. Being that the MPG will vary incredibly based on towing load and payload, as well as engine choice, the MPG cannot be set with any real accuracy. This may put off some buyers. However, those that are looking for a truck with real heavy-duty features will be happy to know that the 2008 GMC Sierra 2500HD 2WD has all of the attributes needed. A robust build, optional crew cab, long or short box, and incredible payload and towing capacity round out the Sierra's list of big boy features. While the price is a bit high, buyers will content knowing that they certainly get what they pay for in the 2500HD. Also, GMC offers warranty options that simply surpass the competition.
