"When empty, the 6.2-liter makes the Silverado an unlikely rocketship. Even at elevation, acceleration felt like 0-60 runs would register around six seconds, suggesting low-to-mid fives might not be out of the question at sea level.
My test rig felt similarly unperturbed when a 6,000-pound trailer was strapped to its hitch. The High Country is rated to tow over double that figure, but given the area's 6,000-plus foot elevation, it still felt like an impressive performance.
Despite having so many options at its disposal, the 10-speed gearbox rarely felt indecisive. I do wish it wasn't necessary to drop the column shifter a notch before using the rocker switch to toggle through the ratios. This requirement feels unnecessary, and it's annoying when you want to quickly call up extra engine braking on descents or preselect a lower gear ahead of a passing maneuver."
