There’s something to be said for an athlete, after what seems to be a lifetime of hard work and dedication, commits him or herself to yet another glorious victory. It’s the attributes of sacrifice, dedication and resolution that separate the truly committed and successful from the scores willing to try something casually once or twice. It’s no great leap to compare enthusiasts devoted to the custom truck realm to those hardcore athletes; the two passions definitely share a similar level of focus. Nathan “Stewart” McGregor (aka Peabody) is one of the elite few highly motivated truck enthusiasts, and he’s rediscovered time and time again what it means to tether one’s heart to the industry.


“A constant hunger lingers within him, driving him to continue creating, sharing and showing his trucks.”

Stewart’s nearly quarter century in the truck scene has been one colored with diverse projects, highs and lows, extreme loss and major wins. The rides that he’s previously owned and built include a Nissan Hardbody, a body-dropped Chevy Astro van, Chevy short-wheelbase dually and a Toyota Tacoma, which was also bodied. Some might suggest that after length of time burnout would set in, but this hasn’t been the case for Stewart. A constant hunger lingers within him, driving him to continue creating, sharing and showing his trucks. His second family, club Negative Camber, has helped feed the flames of his passion throughout the years.



The Italian black mamba leather with black suede inserts only further accentuates overdrawn’s high-class look and feel.

When this now-stunning ’12 Chevy Silverado came on the market, Stewart was more than interested. Nevertheless, his efforts were thwarted when, as he put it, “fate wielded its evil hand,” and the Silverado was sold before he could strike a deal. Fortunately, the truck’s second owner knew there must be a better home for the truck, one that allowed its owner to drive her as often as they pleased, so just a little more than a year after the initial sale, the truck was back on the market. Stewart didn’t hesitate, and he and his buddy, Jeff Phiffer, set off to purchase the truck and drive it 1,800 miles back home. Once the truck was in Stewart’s hands, LST inspiration led to SEMA goals, driving him to act quickly. His first step was to strip it down to the frame and refresh the entire drivevline.


Next up, he perfected the rolling chassis and air suspension, including the addition of upgraded 3/8-inch stainless steel hard lines throughout. With help from John Adkins and Eric Saliba, 16-inch Wildwood disc brakes were installed on the build now known as Project Overdrawn. Suspension work was completed by Phat Phabrikations using a combination of custom spindles, a wishbone 3-link, 2,600-pound airbags and an Air Lift Performance management system. The new setup allows Overdrawn to really lay it all out on the pavement to tuck the all-new staggered 26×9.5 and 26×10 Billet Specialties wheels. The high heels are complemented with 295/30/26R and 305/30/26R Durun tires.


The staggered 26-inch billet specialty BLVD 85 wheels paired with the 16-inch Wilwood brakes really make a statement and provide a winning combination of custom and class.

To change up the overall look, Jeff Phiffer of JustAtTheHouse prepped the body, painted the cab and frame and completed extensive body modifications. The specialty paint produced by Sikkens and House of Kolor is a combination custom Blue Pearl and Tangelo Orange. The truck body was meticulously cleaned and smoothed by shaving the antenna, third brake light, gas door, door handles, tailgate handle and bed rails. All emblems and the headlight reflectors were removed, and the taillights were painted candy red. A heavily modified bumper finished off the custom work on the front fascia. The gas filler was relocated beneath the bed behind the tailgate, and the bed floor received its own special custom treatment. All Chevy Silverado HD components, including the hood vents, were removed, shaved, smoothed or bead-rolled to complete the fully custom body appearance.



Project Overdrawn is propelled by a 5.3L Chevy truck motor employing Dirty Dingo LS3 front accessories brackets, a custom LS2 engine cover and an ultra-clean wire tuck performed by Stewart. The 5.3 inhales through an LS2 intake manifold combined with custom air intake tubing and exhales through polished Hedman shorties and Magnaflow mufflers. Todd Jubert was flown in specifically to complete the interior upgrades and installations for Overdrawn’s SEMA debut. He covered the whole of the interior with Italian Black Mamba leather with suede inserts. Black Porsche carpet with blue stitching rests throughout the interior, along with the embossed and pinstriped black suede headliner.


With help from good buddy David Adams, Stewart upgraded the audio system. MB Quart amps are used all around, paired with four 12-inch MB Quart MS1-304 subs and MB mids and highs. The system is controlled and navigated via Apple iPad. Custom door panels for the speakers, a custom dash fitting for the iPad and a custom center console completed the finish work in the interior.

“Overdrawn is more than just a truck, it’s a promise that the faithful will always find trucks rewarding. It’s stories like this that inspire other builders to keep at it.”
