Drivers in Princeton will love the roomy cabin of the 2026 GMC Sierra 3500 HD. The front seats provide 44.5 inches of legroom, giving tall passengers plenty of space to stretch out. A large 13.4-inch diagonal touchscreen sits at the center of the dash on most trims. This screen uses Google built-in apps for navigation and voice assistance, plus it supports wireless phone connectivity and Bluetooth audio streaming.
GMC built this truck with six trim levels to choose from. The Pro trim has vinyl seats and a 7-inch screen, while the SLE upgrades to cloth seating and the bigger display. Shoppers in Kentucky who want more can choose the AT4 or SLT trims, which add heated leather seats, a heated steering wheel, and dual-zone climate control. The Denali goes further with ventilated front seats, a Bose 7-speaker sound system, and 12-way power-adjustable seating.
The top-level Denali Ultimate trim has 16-way power front seats with lumbar support and massage. A 12-speaker Bose Premium Series system fills the cabin with rich sound. Browse our new GMC inventory today at Trice Hughes GMC, 111 Hwy 91 North, Princeton, KY.
