The world of overlanding is often associated with pricey custom rigs and high-end builds. But your next overlanding project doesn’t have to leave your wallet in the dust. The used truck market is full of full-size, diesel-powered 4x4s that can be easily modified to tackle weekend off-the-grid getaways and epic cross-continent expeditions.

Each of these four modern diesel pickups is begging to be transformed into a rugged, reliable overlander by an adventurous DIYer. They offer the best combination of payload capacity, durability, range and aftermarket support, all for less than $20,000.

Happy hunting.

4. 2016-2019 Nissan Titan XD

When equipped with the 310 horsepower 5.0-liter Cummins turbo-diesel V8, the second-generation Nissan Titan XD packs an impressive 555 lb.-ft. of torque and long-range capabilities. These trucks are rated to tow nearly 13,000 lbs. and 4x4 models have a payload rating as high as 2,080 lbs., which means they can pull all your gear and an off-road trailer through challenging terrain with ease.

Unfortunately, the Cummins is known for issues related to its emissions system and fuel injectors, so ask the seller if all recalls have been addressed and the necessary repairs have been made. This is especially important when shopping high-mileage examples.

Overlanders also appreciate the Nissan’s big 26-gallon fuel tank and the engine’s relatively high miles per gallon, which translates to impressive range. In addition, the Titan is equipped with a heavy-duty 6-speed Aisin automatic transmission and a robust 4WD system. The desirable off-road PRO-4X trim added an electronic locking rear differential, skid plates and 18-inch all-terrain tires.

 

3. 1999-2003 Ford F-250 Super Duty

Ford’s massive Power Stroke 7.3-liter turbo-diesel engine is the largest engine on this list and one of the most reliable diesel engines ever built. Known for its mechanical simplicity and abundant torque, the 7.3 was available in the second-generation F-250 and remains popular due to its longevity and aftermarket support. It’s not uncommon for well-maintained 7.3s to run past 500,000 miles. Plus, if you want to increase the power, this engine responds well to modifications.

From the factory, the most powerful versions produce up to 275 hp and 525 lb.-ft. of torque, and those numbers can be doubled quite easily with the right parts and know-how. Unlike the Nissan, the Ford was available with either a ZF 6-speed manual transmission with a very low 5.79 first gear or a 4-speed automatic with a transmission cooler (a 5-speed automatic arrived in 2003).

4x4 models have a solid axle front suspension, which is best for serious off-roading, a tow rating of 12,500 lbs. and payload ratings as high as 2,660 lbs. That’ll haul a lot of overlanding gear.

 

2. 2007-2013 Chevy Silverado 2500HD

If you want the most torque straight from the factory, then you want a second-generation Chevy Silverado 2500HD or GMC Sierra 2500 HD (they are mechanically identical) with the 6.6-liter Duramax turbo-diesel V8. This engine started out with 365 hp and 660 lb.-ft. of torque, then GM’s engineers cranked it up to 397 hp and 765 lb.-ft. in 2011. They also added an exhaust brake to help tow big loads down long, steep grades.

The durable Duramax is easily modified to make huge power gains and GM paired it with a bombproof Allison 1000 six-speed automatic transmission with a 3.10 first gear and double overdrives.

These trucks have a tough torsion bar front suspension, and in 2011 GM added a stronger boxed frame and wider rear leaf springs with more load capacity. These 4x4s are rated to tow up to 13,000 lbs. and were available with a Z71 off-road package that included skid plates and a lifted suspension. Their 34-gallon fuel tank paired with the efficiency of the Duramax allows for long-range travel.

 

1. 2003-2009 Dodge Ram 2500

The third-generation Dodge Ram 2500 tops our list because of its optional Cummins in-line six-cylinder powerplants, renowned for their reliability and power. With proper maintenance, the 5.9- and 6.7-liter engines run for hundreds of thousands of miles, though the 6.7 is known for issues with its emissions systems. Ask the seller if all recalls have been addressed and the necessary repairs have been made.

In 2003, Dodge introduced a new high-output (HO) version of the 5.9 with the quieter high-pressure common-rail injection system. It was rated 305 hp and 555 lb.-ft. of torque, which increased to 325 hp and 610 lb.-ft. halfway through 2004. The Mopar gang cranked it up further in 2007, replacing the 5.9 with the 6.7 (with an exhaust brake) with 350 hp and 650 lb.-ft. of torque ratings.

Like Ford, Dodge paired its turbo-diesels with either a manual or automatic transmission. The burly 6.7 was paired with a 6-speed automatic or a Mercedes-Benz G56 six-speed manual (arrived in 2005), which can be fragile. With the manual, Dodge detuned the Cummins to 610 lb.-ft. to keep the trans alive. If you’re going to crank up the power, get a truck with the automatic.

Quad-cab 4x4s with the long bed offer 1,830 lbs. of payload capacity, plenty for rooftop tents, extra fuel and heavy equipment. The Ram’s solid axle front suspension makes it capable on the trail, while its strong aftermarket support offers endless customization options. Unfortunately, the off-road focused Power Wagon model, introduced in 2005, was not available with the diesel engines.

If you’re ready to escape into the great outdoors, these diesel rigs prove overlanding adventure doesn’t require a six-figure price tag. With a little creativity, elbow grease and a solid plan, you can turn any of these trucks into the ultimate off-road explorer.
