This is a pure electric truck with no liquid fuel. Range varies by battery pack size (20- or 24-module) and tire choice, with GM estimates from roughly 279 miles on off-road setups to over 350 miles on standard wheels. It supports DC fast charging that can add substantial miles quickly when a compatible high-power station is available, plus flexible AC home charging.
Servicing is lighter than a gas truck because there is no engine oil or many traditional fluids. Expect regular tire rotations at 7,500-mile intervals, cabin air filter changes, brake inspections, and coolant checks for the battery and motors. Software updates handle many refinements. Follow the owner’s manual for exact timing, especially after heavy off-road use.
Safety equipment centers on a full suite of driver aids that come standard, including Super Cruise for hands-free highway driving on mapped roads, automatic emergency braking, lane-keeping, blind-spot alerts, and multiple camera views. No independent crash-test star ratings have been published for this generation.
Keeping the truck means protecting the large battery pack with moderate charge levels for daily use and limiting constant DC fast charging. The air-ride suspension and four-wheel steering add capability but benefit from alignment checks after rough trails. Rubber floor inserts and spray-in bedliner simplify cleanup after outdoor adventures.
