1973-77 would mark the sixth generation of Ford’s popular F-Series of trucks. And with help from the purchase of this ’77 F-250 when it was new, the Ford F-Series would become the best-selling truck in the U.S., a position it has held ever since, much to the chagrin of General Motors. With just one repaint about 20 years ago, this truck is largely the way it was built. Located in Seattle, Washington, the bidding has reached $6,100 here on eBay and the seller is confident in his wares by not setting a reserve for interested parties to scale.

What’s the difference between an F-150 and an F-250, you might ask? Well, the F-150 is a light-duty, half-ton class truck while the Ford F-250 is a three-quarter ton, heavy-duty truck. That means that the F-250 has a gross vehicle weight rating (GVWR) greater than 8,500 pounds, while the F-150 is under that threshold (government-specified). Sixth-generation F-Series trucks would earn the nickname “Dentside,” alluding to their styling and it would be the last round of haulers to be derived from the original F-Series introduction in 1965.

This ’77 F-250 comes with a story, which always makes the subject more interesting. The original owner was in the Coast Guard and used it to commute daily from Seattle, putting on less than 70,000 miles over four decades. We’re told he kept the truck in top shape and its present condition tends to support that fastidiousness. When not in use, it would stay under the carport where the photos were taken, which didn’t negatively impact the vehicle as no rust is present, except for a touch of surface here and there.

Changes in lifestyle, family and age led to the fellow selling his house, this truck and other property. That’s where the seller comes in late during 2020. When he got it, the truck was hard to start so he had the carburetor rebuilt and that seemed to cure the problem. Other than a leak in the exhaust, no other mechanical issues are known, and it’s said to run smoothly now. This truck has a 400 cubic inch engine under the hood with an automatic transmission, so it should have no trouble pulling most anything you might have.

The truck looks great inside and out, including the canopy (aka bed cover) that was added by the dealer when new. As a throwback to the era, there is an 8-Track tape player built into the bottom of the dash. Overall, the interior looks to be in great shape and may be original right down to the carpeting. When you get it out on the highway, you’ll feel a slight bump in the ride that the seller attributes to old tires. He believes that two of the Bias-Ply donuts are original, which would be amazing given the mileage on the truck. So, inspecting or replacing anything made of rubber would be a good idea. The brakes may have been redone more recently.

Hagerty estimates the resale value of these trucks to be between $14-26,000 depending on whether you call it Good or Excellent. These one is probably somewhere in between. If you like trucks of this vintage and could pick this one up for under five digits, it would be a good buy. But save the rest of your money for trips to the gas station.
