Used GMC Sierra 2500HD Regular Cab, Extended Cab and Crew Cab: reviews and buying guide.

Used GMC Sierra 2500HD Regular Cab, Extended Cab and Crew Cab Guides by Year:

It is a testament to GMC's commitment to provide customers with top-of-the-line heavy-duty vehicles that as you go up the size scale, the selection never peters out. With the GMC Sierra, once you get into the ¾-ton 2500HD series, there are a wealth of different configurations in both cab and bed sizes.

The 2003 Sierra 2500HD extended cab comes with dual rear-hinged back doors that do not open independently of the front doors and a passenger rear bench seat, translating into up to six-passenger seating. In keeping with GMC's tradition of offering a maximum number of configurations to accommodate the heavy-duty needs of its customers, the 2500HD extended cab offers two bed sizes as well: a short 6.5-ft. bed and a longer 8.1-ft. bed. This means that an extended cab with a long box will have the ability to seat six and still provide a cargo volume of 70.1 cu. ft. Pretty impressive stuff from a full-size pickup.

The Sierra 2500HD crew cab is a full-size, heavy-duty ¾-ton pickup with four full doors. This results in up to six-passenger seating and an even roomier interior than the extended cab version, which also offers six-passenger seating. With all sorts of space on top of the hard-working capabilities of a massive pickup, the 2500HD crew cab is extremely versatile.
