For 2021, the Ford F-Series Super Duty soldiers on having just gotten a few tweaks and updates in 2020 including fresh styling, driver assistance features, more power and this sparkling little off-road package called Tremor.

To call it little, ok is a bit daft. The Tremor package at $3975 is hardly small, adding a step-up from the FX4 off-road package with taller springs by some 2-inches. Also included are better off-road shocks, extra skid plates, running boards from the Raptor and of course a decal just to name a few things.

Add in the 6.7-liter Power Stroke diesel engine now with astounding 475 horsepower and 1050 pound-feet of torque and its brilliant 10-speed automatic transmission, now you have a contender to the RAM Power Wagon and GMC Sierra AT4 worth looking at.

Styling adds include a nice set of 18-inch alloy wheels in satin black, some Goodyear Wrangler 35-inch all terrain tires and body color fender lip moldings. Ours was also optioned with the factory installed 12,000 pound Warn winch. Nice.

Inside our Lariat plus upgraded tester were several gadgets including the knob for the same pro trailer backup assistant found in the F-150. The system allows you to steer your trailer in reverse using the knob and rear view camera for a more intuitive experience for those not practiced in trailer backing.

Also from the F-150 are a myriad of semi-autonomous safety and driver aids including adaptive cruise control, forward emergency braking, automatic high-beams and lave departure assist.

Our 2021 Ford F-250 Lariat Tremor was near fully loaded with a sticker price of $77,745. You can still spend a might bit more by adding a few more stand alones and the big glass roof but we’re close to the top here.

In our week with the truck we achieved 16 mpg which is similar to our experience in past Super Dity diesel tests including the 2020 King Ranch F-350 we tested last year. Power was impressive though the 10-speed transmission and we were impressed as always with this powerteam.

Suspension on our tester was well balanced and compliant for off-roading, offering plenty of travel over the rougher stuff. It’s a great package chassis wise, but the aluminum built cab still feel flimsy and rattles incessantly on the back roads.
