In the diesel world, no one has more fun or builds bigger, badder trucks than Dieselsellerz. They turn a rusty 1948 Willy's Jeep into a diesel-drinking monster for a new client and find the next giveaway truck at a gas station: a pristine LBZ Duramax.

Heavy D, Diesel Dave and the Dieselsellerz crew scramble to salvage their Duramax giveaway after it goes up in flames. Heavy D ignores Redbeard's strict budget restrictions to turn their company tow truck into a tricked out, lifted monster.

When The Muscle buys a battered El Camino to fix and flip, it might be too big a job for even the Dieselsellerz team to transform it. Heavy D and Diesel Dave find their next giveaway truck- a Ford F650 that's a perfect platform for pure power.

Heavy D comes up with a plan to rid the world of minivans by making and selling a mini version of Dieselsellerz' legendary MegaRam. The F650 giveaway reveal will stretch the power of diesel to the limit when the F650 tries to pull an entire train.

A client asks Heavy D and his crew to turn his beat-up work truck into an off-road mobile service station. Heavy D searches for the next giveaway truck, and Diesel Dave finds the Holy Grail: a 2nd generation, quad cab Dodge with a 12-valve diesel engine.

The Dieselsellerz are cranking out their next giveaway: a quad cab Dodge with a 12-valve. When Black Rhino tools asks the guys for a show-stopping build for a trade show, they pull out all the stops- including importing a surprise from Sweden.

The Dieselsellerz are pulling out all the stops to build a cool hybrid for their good friend and stunt driver Tanner Godfrey. Meanwhile, time is running out for Heavy D to find a show stopping build for the upcoming SEMA trade show in Vegas.

Last year the Dieselsellerz put their insane builds on the map when they debuted their legendary MegaRam at the SEMA trade show in Vegas. With less than two weeks to go, it's all hands on deck to finish a 6-wheel drive F550 in time for the big show.
