The bed extender is part of a $500 package that includes a trailer hitch receiver. The package doesn’t increase towing capacity, however, which with four-wheel drive stays at 6,100 lbs, more than enough for the bike or personal watercraft trailer.

Our test 2013 Nissan Frontier PRO-4X was equipped with the Rockford Fosgate premium audio system, and sitting still, it’s an impressive piece of sound engineering. Underway, however, it has to work against the road noises of an offroad-equipped truck. The tires don’t whine like the dirt tires of yore, but they’re not rigged for silent running either. The overall unsprung weight, the firm shocks and what’s-now a tall 78-series sidewall result in more bounce after a bump than we’re used to. The offroad lugs of the tires will also produce noticeable “walk” in driving around cloverleaf ramps or other extended curves. It’s nothing that can’t be lived with. It’s just what it is.

Nissan made concession to aerodynamics for an edge up on fuel economy, including a deeper front spoiler, sealing off the gap between the cab and the bed, and reshaping the tailgate spoiler. Apparently it worked. Last year’s Frontier was rated at 14/19 mpg city/highway. The 2013 carries a 15/21 mpg EPA rating. Our observed fuel economy with the PRO-4X was 16.0 and 18.0 mpg on successive full tanks, the latter primarily highway miles. Our earlier test of the 2012 Frontier SV, a model possibly friendlier to fuel economy, resulted in only 14.9 mpg. Of course, there’s more to mileage than the wind—driving conditions and routes in particular—but that’s a big difference

The smaller size of the Frontier, compared to the Nissan Titan, means better fuel economy as well. Officially with a 12/17 mpg EPA rating, our driving of a 2012 Nissan Titan Crew Cab yielded 14 mpg. The Frontier, however, is easier to drive in traffic and in congested areas, and for drivers who need a Large rather than XXL, the Frontier is a better fit.

And if going means going off the paved path, the 2013 Nissan Frontier PRO-4X is the way to go.
