International's XT (Extreme Truck) series, produced by Navistar from 2004 to 2008, holds the title for the largest production pickup trucks ever built. The lineup included three distinct models: the CXT (Commercial), RXT (Recreational), and MXT (Military). The CXT, based on a Class 7 dump truck chassis, is the biggest of the bunch, standing over 9 feet tall. The RXT offered a lower stance and more creature comforts, while the military-inspired MXT brought aggressive 4x4 styling to the platform.

Collectors are drawn to the XT series for its unparalleled road presence and absurdity. These aren't just large trucks; they're medium-duty commercial vehicles with a pickup bed, creating a spectacle wherever they go. The MXT is often the most sought-after for its unique design and more manageable dimensions, while the CXT is the ultimate expression of size. With very low production numbers, their rarity adds significantly to their appeal.

Buying Tips

  • These are commercial trucks, so inspect the frame and chassis for rust and stress cracks, especially if it has a history of heavy hauling or snowplow use.
  • Know the engines. The CXT's DT466 is robust, but the MXT's VT365 V8 (Ford's 6.0L Power Stroke) can have EGR and head gasket issues. Ask for proof of "bulletproofing" modifications.
  • The custom interiors were low-volume assemblies. Test every switch, gauge, and electronic feature, as finding replacement trim and components can be nearly impossible.
  • Tires are a major expense. A full set of commercial-grade tires can cost over $5,000, so factor the current tire condition and age into your offer.
  • Air brake systems on the CXT require specific knowledge. Check for leaks in the lines and ensure the air compressor and dryer are functioning correctly.
