Overland Classifieds :: Nitro Gear Ford Superduty 4×4 RV

At first glance, today’s classified appears to be an EarthRoamer, but it’s a one-off custom build. The Nitro camper began as a 2004 Xplorer Xcursion RV on an F-450 4WD chassis and has been completely reimagined and heavily modified to create a go-anywhere expedition vehicle.

Look familiar? Chris Cordes featured the build on Expedition Portal in 2018; it has also been published on nitrogearaxle.com and treadmagazine.com. Make no mistake, this vehicle is more than just a big set of wheels, tires, and a lift kit—it’s a carefully engineered off-grid rolling home. While the Nitro Gear camper may not have all of the premium features included in a used EarthRoamer, it’s less than half the price, though certainly not half the vehicle.

From the Seller:

“I have owned this camper for almost 10 years and have used it for events and camping all over the West Coast. It is very capable and only limited by its size. A lot of my camping has been during the wintertime for ski season, and this rig has allowed me to be self-contained and comfortable off-grid (it required a lot of time and dollars to winterize everything).

It’s easy to drive, effortless on the highway, tows comfortably, handles well, and has a tighter turning circle than a stock F-250. It’s also easy to park and can fit in a single space if backed in over the curb. Thanks to the slide-out rear bedroom and cabover bed, it easily sleeps a family of four or more. The truck itself has done just 85,000 miles, and the Cummins motor (swapped at 40,000 miles) has done a similar mileage.”

New Dynomite Diesel 50-horsepower injectors were fitted at a cost of $4,000 just 3,000 miles ago.
