So, you want a turbodiesel-powered vehicle that has twice the cargo space of a Suburban or Excursion, but can also crawl through the mud and rocks like a trail rig? Time to start shopping for a Hummer H1? Nope. You want a van, a Quigley 4x4 van, and you didn't even know it.
Quigley has been building custom fullsize vans since the early 1970s and is famous for its 4x4 conversions like these vans seen flexing on the rocks of Moab, Utah. The Ford Econoline is equipped with the 6.0L Power Stroke engine, a Dana 60 front axle from an '05 F-350 pickup, a standard Dana 60 rear, a five-speed Torqshift transmission, and a NV271 manual transfer case. The Chevy has the 6.6L Duramax, a Ford Dana 60 front axle (swapped for the stock IFS), a Dana 70 rear, a manual NV261 transfer case, and a four-speed 4L85E automatic transmission (since the Allison 1000 will not fit under the floor of the van). The suspension upgrades provide both vans with about 3-1/2 inches of lift over the stock ride height.

Under the hood of the Ford, you can see the top of the 6.0L Power Stroke engine, rated at 235 horsepower and 440 lb-ft of torque. It is hooked to a five-speed Torqshift transmission, which sends power to a NV271 two-speed manual transfer case. |
The standard 35-gallon Ford fuel tank had to be replaced with a modified 31-gallon unit to make room for the large transfer case. The stock radius arm, I-beam independent front suspension is removed by Quigley to make room for a stronger solid axle. The coil-sprung Dana 60 with manual locking hubs is sourced from '05 Ford F-350 trucks and is located with a four-link setup. | 
The suspension modifications give the Ford van about 3-1/2 inches of extra clearance over the factory ride height. This improves the approach and departure angles, along with increasing the breakover angle. |
The Ford's rear suspension features the original Dana 60 solid axle on leaf springs. The factory's four wheel anti-lock braking system remains intact and functional. | |
