International Harvester XT

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.

The market for these trucks is thin but dedicated, leading to a wide range of values. The average sale price hovers around $72,000, but condition, mileage, and model are critical. An MXT in excellent condition will command a significant premium over a work-worn CXT. As symbols of early 2000s excess, they maintain a strong cult following that keeps values from falling into typical used commercial truck territory.

Recent sales show a wide spread, with prices for International XT models ranging from $24,000 for well-used examples to $120,000 for pristine, low-mileage trucks.
