In addition to the lineup of full-size SUVs based off the all-new GMT900 platform, General Motors took the opportunity at the North American International Auto Show to show off the biggest truck they offer. Based off the Chevrolet Kodiak platform, a work-only medium-duty commercial rig, this white monster towered over all the vehicles around it. The concept vehicle is a real truck that offers all the options available from GM's corporately connected outfitter, Monroe Truck Equipment. Located adjacent to the plant where the Kodiaks roll off the line, Monroe has added an UltraRide air suspension to the rear axle, a polished bed rail, retractable tonneau cover, dual side pipes, a spray-on bedliner, premium leather seats, a DVD entertainment system, a fifth-wheel trailer hitch, and a custom wood console. The tires are almost 38 inches high, with the aluminum wheels standing 19.5 inches in diameter. Other special features include a custom drop rear bumper hitch, fold-flat rear bench seating (for sleeping), and a wood grained trimmed dash. Since this vehicle has been out for over a year (we had the original on Truck Trend's cover in Sept/Oct 2003, and the updated 4x4 model in our Jan/Feb 2005 issue), our guess is when the higher-up at GM found out that Ford was working on the F-250 Super Chief, they knew they needed something in the "big truck" arena to match it. We're not sure the Chevrolet Kodiak 4x4 Monroe Bed Concept truly matches the Super Chief, but we like the Kodiak's muscle factor. We score it a 10.
