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. Compare Sierra Cargo Solutions at Henry Brown Buick GMC The Sierra 1500 offers traditional pickup versatility with up to 89.1 cu. ft. of bed volume and an available 6-function MultiPro™ Tailgate. Sierra EV takes a different route with its available 10-ft.-10-in. MidGate configuration, power-open eTrunk™, and up to 10.2 kW of available off-board power.

Tire alignment is one of those fundamentals that rarely gets attention until something feels wrong, yet it plays a central role in how a vehicle behaves every mile it travels. For Buick and GMC owners in Gilbert, AZ, correct alignment preserves the integrity of the chassis, protects the tires, and keeps the vehicle driving with the balance and composure its engineers intended. When alignment drifts out of specification, the effects are subtle at first. Steering response loses its precision, tires begin to wear unevenly, and rolling resistance quietly increases. Over time, those small inefficiencies compound, affecting fuel economy, ride quality, and long-term component durability. Proper alignment keeps suspension geometry working in harmony, allowing the tires to track straight and maintain consistent contact with the road surface. more How Often Tire Alignment Should Be Checked A practical guideline for tire alignment is every 6,000 to 10,000 miles or once per year, but real-world conditions often dictate more frequent attention. Rough pavement, curb impacts, potholes, and repeated stop-and-go driving can all nudge alignment out of tolerance. Buick and GMC vehicles are built with robust suspension systems, yet even the most carefully engineered platforms respond to the realities of daily driving. Regular alignment checks help restore factory specifications before uneven wear patterns take hold. Addressing alignment early protects both tire investment and suspension components, maintaining the composed ride and predictable handling these vehicles are known for. How to Recognize Alignment Issues Early Drivers often sense alignment issues before they see them. A vehicle that consistently pulls to one side, a steering wheel that no longer sits centered on straight roads, or vibration through the steering column are common indicators. Tire wear patterns can also tell a clear story, particularly when wear appears concentrated on inner or outer edges. Ignoring these signs allows unnecessary stress to build throughout the suspension and steering systems. Correcting alignment promptly keeps the vehicle stable, predictable, and efficient across a wide range of driving conditions. Long-Term Benefits of Proper Alignment Consistent alignment maintenance delivers tangible benefits over the life of a Buick or GMC. Tires last longer and wear more evenly, fuel efficiency remains closer to factory expectations, and steering response stays crisp and controlled. Just as importantly, correct alignment supports safe handling during sudden maneuvers and changing road conditions, where stability matters most. For drivers in Gilbert, AZ, alignment maintenance is less about fixing problems and more about preserving performance—keeping the vehicle operating as a complete, balanced system.
