For Sale: 60k-mile 1990 GMC Sierra Dually with crazy bodywork

Back in 1990, spending $34,870 on a pickup truck is the equivalent of spending just over $71,000 today. Which… honestly, that’s where full-size trucks are at right now, as crazy as that sounds. Still, that’s a lot of coin for a 1990 pickup but that’s what the original owner of this GMC Sierra C3500 Dually spent back in the day. And that’s because they added on $12,820 for something called the Tridon conversion kit. And now this piece of fiberglass wonder can be yours for $14,995.

The truck actually looks to be in great shape minus the fading paint. It has a 454 under the hood with just 60,000 miles on the clock. And the seller states they just completed a ton of work on the sort of things that need to replaced for a truck of this age with that mileage. We’re talking belts, filters, pumps, wires, sensors, etc. On top of that, the interior is excellent.

Is it an ugly thing? Absolutely. Is there a good truck under that bodywork? Most certainly. And with the used market the way it is, a 60k-mile heavy-duty truck for less than $15k sounds like a good deal. And if you really want to clean up that paint, you’d have something pretty amazing to bring to the next Radwood as well.

The truck is listed for sale in Culver City, California on Craigslist. Go there for more pics and more information.

  1. The unique offspring of an aging ’75 Trans Am having a love affair with a hot young ’89 Mitsubishi Starion.

    A giant enfant terrible with 454 ci of TBI strangled combustion chambers awkwardly motivating its bulk through a non-electric shift, non-overdrive slushbox, and wobbling to each stop on some of the worst designed front brakes in history.

  2. The pure opposite of “timeless”, I guess, but I agree on your take about a decent used truck. This vehicle has been treated well, and that counts for a lot.

    1. Right, it looked dated as soon as it was finished. The interior is in great shape, apart from the wood treatment that would look at home in a 1960’s RV, which again was that bad from day 1.

  3. The Tridon package was another offering from Knudsen Automotive Designs, which also produced the Tojan–the ultimate 3rd gen F-body, blessed by Pontiac:

  4. This looks like something built for an 80s “high concept” TV show/movie where the pitch to Glen A. Larson or whoever was, it’s like Knight Rider but WITH A TRUCK!!

    1. My first thought was paint that in some brighter colours and it looks like a background vehicle from Baz Luhrman’s Romeo + Juliet.

    1. I think the right buyer would be OK paying 15 grand for a low mileage OBS 3500 in good condition, with or without the bodykit. I think the paint renders this one to be in less-than-good condition. A repaint would remedy that, but all that bodywork is going to make it an expensive paint job.
