Kenworth K370 • Cummins 9L • 425 HP / 1,250 LB-FT • Allison 3000 • Locking 6x6

Offered for sale is an exceptionally unique 2020 Global Expedition Vehicles Patagonia, combining GXV’s premium composite expedition habitat with an extensively upgraded 6x6 chassis and powertrain 

This is not a standard GXV build. The original expedition platform underwent an extensive second-stage mechanical build that dramatically increased power, torque, traction and drivetrain capability.

Originally built as a 4x4 with a 260 HP / 660 lb-ft powertrain and Allison 2000-series transmission, this Patagonia subsequently underwent a major mechanical transformation. It now features a 425 HP Cummins 9-liter diesel, Allison 3000-series transmission, substantially upgraded transfer case, locking 6x6 drivetrain, upgraded cooling system, and custom rear motorcycle/twin-spare lift.
