Let me be clear—I do not want to suffocate and die. Not by polluted air, not in any of my personal relationships, and certainly not under a wave of sea water down 5th Avenue.

But the Chevrolet Kodiak C4500, and its sibling GMC TopKick, have technically been . On the commercial side, they served society as hardworking dump trucks, plow trucks, school buses, and the sort. But a batch of them were also sold as giant street trucks, modified from the factory by a company called Monroe Truck Equipment.

This one, listed on ,is a red Kodiak model that’s rear-wheel drive with 48,000 miles on the clock. The listing claims it’s a six-cylinder diesel, and there were a couple different ones available. This could be the 7.2-liter Caterpillar I-6 or the 7.8-liter Duramax-badged Isuzu 6H. Either of the two offers plenty of torque to motivate this monster.

called the Kodiak and TopKick an “almost rational” decision compared to a Hummer, so move now before the next recession hits and gas isn’t cheap anymore. This could be our last chance.
