Six-Door Ford F-450 Looks Expensive. Its $1,038 Fuel Bill Agrees

A stretched 2020 Ford F-450 Platinum capable of seating 11 was listed on eBay.
The build adds a third row and a third axle set on 46-inch tires at full height.
A twin-turbo kit lifts the 6.7-liter PowerStroke well past its stock 475 horsepower.

The custom truck scene rarely lacks for excess, but this Ford build takes things somewhere else entirely. When it popped up on eBay, it looked almost too strange to be real. Yet this isn’t some AI fever dream, it’s a genuine creation that initially carried a $400,000 asking price. Or rather, it did, as the listing reportedly closed with a sale last night.

It starts life as a 2020 Ford F-450 Platinum, already massive by any reasonable standard. That clearly wasn’t enough for the company behind it, Stretch My Truck, which leans into its name with zero restraint and pushes the idea of “big” well past the point of restraint.

The ladder-frame chassis and body have both been stretched, making room for an extra pair of doors and a third row of seating. The end result borders on absurd in scale, with a footprint closer to a loaded semi than a pickup, seating for up to 11 passengers, and an 8-foot bed bringing up the rear.

The cabin keeps the Platinum-trim features of the donor truck but adds a reworked infotainment setup, now centered around a larger touchscreen and extra displays mounted in the seatbacks to keep passengers occupied. It also gains power-adjustable second-row seats, along with additional heating and air conditioning units in the rear.

The real party piece is a bespoke suspension system that can adjust ride height independently at each axle, which explains those exaggerated squatting stances. At full extension, the F-450 rolls on towering 46-inch tires with dual wheels at the rear. For anything resembling normal use, including towing, it can drop down to a more manageable set of 36-inch tires.

Under the hood sits a massive 6.7-liter PowerStroke V8 diesel, now running a twin-turbo setup, a custom intercooler, and an ECU tune. While the seller hasn’t provided specific output figures, these modifications suggest a significant jump over the stock 475 hp (354 kW / 481 PS) and 1,050 lb-ft (1,424 Nm) of torque.

Long-haul range gets a serious boost thanks to extra fuel storage. There’s a 60-gallon (227-liter) tank tucked under the cab, plus a 75-gallon (284-liter) transfer tank in the bed. Add in the original 50-gallon (189-liter) tank, and total capacity climbs to roughly 185 gallons (700 liters).

And yes, you’ve probably already done the math. With diesel averaging $5.610 a gallon across the US, filling it from empty comes out to about $1,038. Ouch.

The elongated F-450 shows 13,709 miles (22,062 km) and presents in pristine condition. Its build reportedly swallowed just shy of $500,000. The eBay listing set the ask at a steep $399,900, which, apparently, wasn’t enough to scare off a buyer. That puts it at more than four times the price of a factory-fresh Ford F-450 Platinum.
