Ford is betting that there are lots of truckers out there who want that comfort but don't need a full cargo bed. The F-150 SuperCrew combines full-size back doors, a genuinely roomy back seat, and a 67.2" cargo bed. Overall length is only 18.8', but keep in mind the SuperCrew still needs more than 40 feet to make a U-turn. A 4.6-liter V-8 is standard, or you can upgrade to the 220-hp, 5.4-liter V-8 that we tested. Both engines are modern designs with overhead cams. We hitched the SuperCrew to a 21' Sea Ray Sundeck on a Trail Rite tandem-axle trailer. The towing weight was 4,690 pounds, nearly two-thirds of the maximum recommended load. Yet, this rig never broke a sweat - even while climbing the long, steep grades we found east of Irvine, California. With an 11.6' wheelbase and 2.5-ton curb weight, the SuperCrew burned about 7 mpg.
