Pick of the Day: GMC pickup has Tridon Conversion treatment

Fiberglass coachwork transforms dually truck’s appearance


It might take a few minutes to figure out just what comprises the Pick of the Day, which is being advertised on for $19,995 by a private seller in Los Angeles.

At first glance it might looks like a modified Chevrolet Avalanche. But it is not. What is it? A 1990 GMC Sierra C3500 Dually with an extended cab and a Tridon Conversion kit. 

The ad states Tridon Conversions were a $12,820 option offered by some dealerships. In the case of this C3500 with four rear tires, that option represents more than a third of the vehicle’s original $34,780 price. 

According to the seller, who references an exotic vehicles web page, in 1978 Russ Knudsen started an automotive design company in Omaha and put Stutz- or Ferrari-style fiberglass coachwork on contemporary vehicles. Knudsen’s company was succeeded by Rage Exotic Vehicles, a company that included Knudsen’s son, Andrew. The company’s produces, the website notes, have been described as “Mad Max meets James Bond.”

This Tridon Conversion GMC has been driven little more than 60,000 miles in its lifetime, has a “flawless” interior and has been retrofitted with “ice cold” air conditioning the seller notes.

It recently has received a new water pump, starter, rear main seal, distributor, fuel pump and fuel tank, spark plugs, belts, power-steering pump, and more.

The truck is powered by a 454cid V8 engine linked to a 3-speed automatic transmission.

However, the seller notes that the paint has faded and there’s a “half-dollar size perfection on the front left bumper.”

Fresh paint would “bring it back to its Old Glory Days,” the seller suggests, adding that the result would be a spectacular truck for “towing or show.”

  1. Asking $20,000. A great UNIQUE , 1 of a kind- awesome truck. 60,00 miles? AND>>> a 454! This will hold it’s value. And make a real impression til you sell it. And.. I am not a truck person.

  2. I think it’s cool and unique . But it would bring more money like 12k tops if it were just a basic truck . It’s all plastic spoilers and wood

  3. Buyers nowadays do not want a “ gas guzzler” plus it’s already lost 40% of the original cost & will only continue to depreciate more.

    • Oh I don’t know about that Ravi,
      It’s not supposed to be a daily driver. I think for an occasional use vehicle, to tow your boat or camper to the lake, it would be unique, and a heck of a lot cheaper than a new dually or even a newer used dually.. If it were closer to where I live, I might buy it myself.
