What is the GMC Sierra 1500 interior like for El Paso drivers?
The 2026 GMC Sierra 1500 interior is a full-size truck cabin, and the seating, screen and storage choices change by trim. Group 1 GMC Westside, at 955 Crockett St in El Paso, sells new Sierra 1500 trucks, so you can sit in those cabins before you decide.
Keep reading below, then schedule a test drive in El Paso. Bringing your own numbers to the lot settles this faster than any spec sheet.
What do you get inside a 2026 GMC Sierra 1500 crew cab?
The crew cab seats up to six on most trims. The Denali and AT4 seat five. Those seat counts are GMC’s own published numbers for each trim, so they tell you how many people fit at the table before you look at anything else.
Crew cab legroom in the front row is 44.5 inches, and the second row measures 43.40 inches. The Double Cab’s back row is shorter at 35.24 inches. If you carry adults in back, the crew cab is the one to sit in.
What seat features does the Sierra 1500 offer up front?
Seat features depend on the trim. The AT4 comes standard with heated and ventilated perforated leather front seats, the Denali with 12-way power front seats with power lumbar, and the AT4X and Denali Ultimate with 16-way power heated and ventilated front seats with a massage feature. On the Pro, a 10-way power driver seat with power lumbar is available. You will not find those on every trim, so check the trim sheet when you sit down.
How much room is there in the Sierra 1500 back seat?
Back-seat room is the number to test in person. The crew cab’s second row gives 43.40 inches of legroom, and the Double Cab gives 35.24 inches, according to GMC’s published 2026 Sierra 1500 specifications. The gap is wide enough that the cab you pick should follow who rides in back.
How much cargo does the Sierra 1500 bed hold?
Cargo volume depends on the bed. GMC publishes 62.9 cubic feet for the short bed and 71.7 for the standard bed, in the 2026 Sierra 1500 specifications. Those figures are cargo volume, so they tell you how much stuff the bed holds, not how much fits in the cabin.
How does the Sierra 1500 interior change from trim to trim?
The main interior differences come down to seating and equipment. GMC lists the Pro, SLE, Elevation and SLT at up to six seats in the crew cab, and the Denali and AT4 at up to five. The AT4 is the trim with heated and ventilated perforated leather front seats, and its Jet Black interior with Kalahari accents sets it apart from the rest of the lineup.
Price is the other way the trims split. Starting MSRP runs from $38,300 for the Pro up to $84,400 for the Denali Ultimate, and the trims in between each carry their own price. Work out which seats and screen you want, then match them to a trim that fits your budget.
What does a 2026 Sierra 1500 cost for each trim?
GMC’s starting MSRP for each 2026 Sierra 1500 trim is the price to start from. The Pro starts at $38,300, the SLE at $48,700, the Elevation at $50,500, the SLT at $55,100, the Denali at $66,100, the AT4 at $67,000, the AT4X at $79,600 and the Denali Ultimate at $84,400. Those are starting prices, and the figure on a truck you can buy depends on options and equipment.
Come to 955 Crockett St and compare two or three trims side by side in the same visit. Bring your budget and the seat count you need, and let the numbers decide which trim makes the cut.

In a May 2026 5-star Google review, Ralph R. wrote: “I was on the hunt for a GMC Canyon Pickup Truck in Las Cruces, Tucson, Albuquerque, and El Paso with no luck, until I called Shamaley Group one. I reached out to Group 1 and asked for a salesman, and Guillermo was right there to help me find the perfect truck. We worked together seamlessly, without any haggling or wasting time for neither one of us. Guillermo demonstrated and was always professional and courteous, which made the whole experience great. Guillermo was super professional, committed, and friendly. He was great at communicating and answering my questions quickly and efficiently. With his financial manager, they were able to give me an amazing deal on my 2026 Canyon AT4. They even had the truck ready for pickup and all the paperwork ready to sign, so we were in and out in just an hour and a half. Guillermo explained all the truck systems and showed me all the instruments thoroughly, as well as the On-Star and GMC app. I highly recommend Group 1 for any future vehicle sales. I’d definitely recommend this business to others. I can’t wait to take my truck to the service center in the future! Thank you Shamaley Group One for all your work and finding me the truck I was looking for! With highest respect, Ralph Ramos”
