Pickup trucks exist largely because humans own things that are inconveniently shaped. Lumber is long. Coolers are bulky. Bicycles refuse to stack politely. The 2026 GMC Sierra family attacks this problem from 2 directions. The Sierra 1500 offers 3 bed sizes and the available MultiPro™ Tailgate, while Sierra EV adds an available MultiPro™ MidGate, a power-open eTrunk™, and available Energy Transfer capability. For Gilbert, AZ, drivers, the choice comes down to what needs carrying, how long it is, and occasionally how many electrical devices need power once you arrive. Three Sierra 1500 Beds, Because Trucks Have Different Jobs The Sierra 1500 offers Short, Standard, and Long Bed configurations, with availability depending on cab and trim. The Short Bed provides 62.9 cu. ft. of cargo volume, the Standard Bed expands that to 71.7 cu. ft., and the Long Bed reaches 89.1 cu. ft. The Pro Regular Cab can be configured with a Standard or Long Bed, while Crew Cab configurations balance rear passenger room with bed space. That's an important distinction because a truck hauling 4 coworkers has different packaging requirements from one spending its life carrying tools, materials, and equipment. MultiPro™ Turns One Tailgate Into Six The available MultiPro™ Tailgate gives Sierra 1500 owners 6 configurations without requiring them to keep 6 tailgates in the garage, which would admittedly defeat the point. It functions as a conventional primary gate but can also provide a load stop for longer cargo, easier bed access through the inner gate, and a full-width step. The inner gate can serve as a work surface for compatible equipment as well. The advantage is straightforward: the bed itself doesn't change, but the way you load, secure, reach, and work around its contents can. The Sierra EV Can Make Room for 10 Feet 10 Inches of Cargo The Sierra EV approaches long cargo differently with its available MultiPro™ MidGate. Fold the rear seats, remove the rear glass, open the MidGate, and deploy the MultiPro™ Tailgate load stop, and available cargo length expands to 10 ft. 10 in. That creates space for longer equipment without permanently sacrificing the Crew Cab cabin. Close everything again and the rear passenger area returns, allowing the truck to alternate between carrying people and carrying objects that seem determined to be longer than a pickup bed. The eTrunk™ Gives The Sierra EV Another Place to Put Things An electric truck has no gasoline engine in the front, so GMC has turned that space into storage. Sierra EV's power-open eTrunk™ provides a lockable, weatherproof compartment for tools, luggage, charging equipment, and other gear. It also gives owners somewhere to separate smaller or more valuable items from whatever is bouncing around in the pickup bed, which could be muddy camping equipment, building supplies, or something purchased at a hardware store after saying, “I'm pretty sure it'll fit.” The Sierra EV Can Power More Than the Truck Available Energy Transfer provides 7.2 kW of off-boarding power along with a 240-volt bed-mounted outlet. Available Energy Transfer Pro increases total off-boarding capability to as much as 10.2 kW when equipped with the required GM Accessories PowerBar+. The Sierra EV also offers 800V DC fast-charging capability on compatible configurations. With the Max Range Battery Pack and a compatible charger, GMC estimates it can add approximately 120 miles of range in 10 minutes, making the electrical system part of both the truck's propulsion and its ability to support equipment away from home.
