Ford is readying up to refresh its best-selling F-150 lineup. The full-size truck was first caught testing on public roads toward the end of last year. This time, our spies caught another test vehicle but in the Tremor guise, given away by the step boards, skid plate up front, wheels wrapped in chunky tires, bumper-integrated dual exhaust tips, and the unconcealed "TR" decal on the bed's side panel.
Just like the previous sightings of non-Tremor variants, the heavy camouflage suggests that there will be styling changes at the front and rear fascias. One of the spy shots before provided a better look at the taillights, which saw a vertical line angled forward, akin to what you'll see on the electric F-150 Lightning.
