Curb weights sourced from the NHTSA Canadian Vehicle Specifications database and recorded per body style, with fluids and a full fuel tank but no occupants or cargo.

How the figure moved since 2016

The lightest 2016 record is 3,646 lbs; the lightest 2020 record is 3,986 lbs — 340 lbs heavier (9.3%).

At the top of the range the 2020 file reaches 4,489 lbs against 4,385 lbs in 2016, a 104 lbs increase — driven by which configurations exist, not by the same truck gaining mass.

Where the mass sits: 50/50

NHTSA records a 50/50 distribution, so the 3,986 lbs splits to roughly 1,993 lbs on the front axle and 1,993 lbs on the rear.

The two axles are not the same width either: 63.4 in of track at the front against 64.2 in at the rear, 0.8 in narrower in front.

Weights, track and weight distribution from the NHTSA Canadian Vehicle Specifications; powertrain list and MPG from fueleconomy.gov (US DOE).
