CAB TERMINOLOGY
CHEVROLET SILVERADO 1500/2500/3500 / GMC SIERRA 1500/2500/3500s
2014-Current
For Chevy/GMC’s 2014-current Silverado/Sierra 1500 models, they offer a Regular Cab, a Double Cab, and a Crew cab.
As you may have noticed, for Chevy and GMC’s mid-sized cab, this latest body style lineup included a Silverado/Sierra with a differently styled rear door. Much like Dodge/Ram 1500’s Quad cab and Toyota Tundra’s Double cab, Chevy and GMC’s newly renamed medium-sized cab version, called the “Double Cab”, features a slightly larger rear door that does not require the front door to be opened in order for it to open or close.
The older body style Silverado and Sierra 1500/2500/3500 Extended Cabs had the suicide style doors which are no longer available on the latest body style. They do still offer the Regular Cab and Crew Cab options on 2014 and newer 1500 Silverados and Sierras, with the newer Crew Cab offering a larger rear door and more rear cab space than prior body styles.
The Silverado and Sierra 2500/3500 models retained the older body styles until 2015, when they took on the same cab names and styles as their 2014 Silverado/Sierra 1500 counterpart.
Like the previous body style from 2007-2013 (1500) and 2007-2014 (2500/3500), the new 2014-current 1500 Silverados and Sierras and 2015-current 2500/3500 Silverado and Sierras don’t share the exact same bed, although they do share the same inside bed dimensions.
1999-2013
For 1999-2013 models, Chevy and GMC offered 3 different cab styles on 1500/2500/3500 Silverado and Sierra trucks. They are referred to as Regular Cab, Extended Cab, and Crew Cab.
Regular Cab and Crew Cab models had one and two doors, respectively, and the Extended Cab had a “half” rear suicide style door that opened opposite to the front doors and required the front door to be opened in order for them to function.
Despite a body style change in 2003 and then again in 2007, the cab styles kept the same names on all 1999-2006 models and functioned in similar fashion.
Despite Chevy and GMC sharing virtually the same bodies, it is important to mention that, while the cabs were virtually identical, the beds on 2007-2013 Silverados had a different taper on the rear outside corners of the bed than the Sierra did. This applied to the all 1500/2500/3500 models. Therefore, unlike prior years, bed accessories may not be interchangeable between a 2007-2013 Silverado and a 2007-2013 Sierra, unless those accessories fit inside the bed, where the dimensions and designs between Silverados and Sierras were virtually identical.
CHEVROLET COLORADO / GMC CANYON
2015-Current
The new 2015 Colorado/Canyon were brought back to life after being discontinued for 3 years. The new models feature two cab sizes, called the Extended Cab and the Crew Cab, but not a Regular Cab, which was only offered on the older 2004-2012 versions.
The extended cab rear doors function much like the 1999-2013 Silverados/Sierras, where the rear door is a half sized door that can only open when the front door is opened. That is most likely the reason that Chevy did not adopt the “Double Cab” name for the medium-sized cab version of the new Colorado. The Crew Cab model offers 2 full sized front and rear doors.
2004-2012
The first Chevy Colorados and GMC Canyons offered the same cab name and styles as their bigger counterparts. These include the Regular Cab, the Extended Cab, and the Crew Cab. These cab styles functioned exactly like the 1999-2013 Silverado/Sierras mentioned above.
BED TERMINOLOGY
CHEVROLET SILVERADO 1500/2500/3500 / GMC SIERRA 1500/2500/3500s
Since 2007, Chevrolet / GMC have offered three bed sizes for the 1500. They include the 5.8′ bed, the 6.5′ bed, and the 8.0′ bed.
Unlike cab sizes, Chevy has not provided their own terms to describe each bed size. Therefore, aftermarket accessory manufacturers have referred to them with various different terms. The most commonly utilized terms for these beds is “extrashort” or “crew bed” for the 5.5′ bed, “short” or “standard” for the 6.5′ bed, and “full” or “long” for the 8.0′ bed. Only certain bed/cab size combinations are available, so check the Truck Bed and Cab Combinations page to see what possible combinations exist.
The 2007-current Silverado 2500/3500 and Sierra 2500/3500 have 2 available bed sizes, which include the 6.5′ shortbed, the 8.0′ longbed. They are also offered in the 8.0′ longbed dually, or dual rear wheel bed. The 2500/3500 models are not available with the extrashortbed 5.8′ bed.
For 1999-2006 Chevys and GMCs, there were only two bed sizes, the 6.5′ shortbed and the 8.0′ longbed.
