A 6.0L Ford F-550 that Gets the Job Done

When tooling down the road, customized work trucks like Rudy Tejeda’s flatbed are always some of the easiest trucks to spot. With huge, 6-inch dual stacks; custom taillights, brake lights, and reverse lights; and a full-on custom flatbed with a fifth-wheel hitch; there’s not much Rudy’s 2004 Ford F-550 can’t do. Rudy was nice enough to take time off work so we could have a look at his very capable Ford.
Since Rudy’s rig is a Ford F-550, it came with some very serious options to begin with, like 4.30 gears and 19.5-inch wheels with low-resistance rolling stock. The ’04 also has Ford’s proven 5R110 transmission, which at nearly 120,000 miles still isn’t missing a beat -- even at modified power levels. Speaking of power, Rudy has pushed past the usual intake and exhaust modifications with the addition of 50hp injectors, a Garrett PowerMax Stage I turbocharger, and custom tuning via an SCT programmer. Rudy’s Ford was also beefed up for reliability by the folks at Brown’s Diesel in Riverdale, California, with the addition of ARP head studs and an upgraded EGR and oil cooler. The result is an estimated 450-plus horsepower, with around 900 lb-ft of torque.

But the business end of the truck is the bed, which Rudy uses for all types of repairs, towing jobs, and metalworking. Starting off the cavalcade of bed-mounted tooling is a Lincoln 305 gasoline-powered welder and a Powermax 85 plasma cutter, which Rudy uses for welding jobs and pipefitting. Since most tasks require on-the-job air, an Ingersoll-Rand air compressor is mounted on the custom flatbed. Rudy also built the truck’s bed himself and chose 304 stainless stacks so they could be polished to a brilliant shine.
As a final nod to the truck’s capability, Rudy indicated he’d moved more than 20,000 pounds around the yard frequently without so much as a hiccup. Our hats definitely go off to Rudy for building a unique and capable 6.0L-powered truck -- and we can’t wait to see what he has in store for his next buildup.

One of the most noticeable features of the custom flatbed is the LED-style taillights, reverse lights, and brake lights, which Rudy purchased from “some local parts store.”

Every working rig should have a brake controller, and Rudy’s Ford F-550 is no exception. A Draw-Tite Activator II trailer brake controller mounted under the dash takes care of stopping any load.

Plenty of storage space was built into the bed in order to store tools and equipment. With two per side, tools remain both close at hand and safe.

Perhaps the most notable feature on the truck is the twin 6-inch stacks, which were made by Rudy himself out of 304 stainless steel.

Since this truck sees a lot of welding jobs, two tanks are held securely to the custom flatbed. They also remain handy, however, for use with a moment’s notice.
