An All-New Seasons of “Dirty Mudder Truckers” and “Diesel Brothers” Premieres December 9 on Discovery Channel [VIDEO]

Everyone’s favorite trucking team is back for a season of bolder builds, bigger trucks with more hijinks, dad jokes, and freestyling lyrics than ever before. Heavy D, Diesel Dave, The Muscle and the rest of the DieselSellerz crew are together again bringing audiences behind the scenes of their epic one-of-a-kind truck builds and an event viewers will have to see to believe. The brand-new season of DIESEL BROTHERS returns Monday, December 9 at 8PM ET/PT on Discovery Channel. Mondays will be Trucking Huge as DIESEL BROTHERS leads into an all-new season of DIRTY MUDDER TRUCKERS, airing Monday, December 9 at 9PM ET/PT.

“This season is chock-full of firsts and sure to amaze audiences coast-to-coast. The dream team at DieselSellerz will attempt to build their first-ever diesel-powered boat, their first electric drag-bike, and their very first mega-truck.” To the DIESEL BROTHERS, nothing is impossible, and no build is too challenging. As Heavy D explains, “Really bad ideas are often the really good ideas.”

Kicking off the season in style, the team first sets out to build a mobile DJ party trailer complete, of course, with a tricked-out truck to pull it. This sends Diesel Dave and The Muscle on a mission to find the perfect square-body truck, not an easy feat since square bodies are more than 30-years-old. And Sam, the team’s “diesel mad scientist” has come up with a plan to power an electric mini drag bike to race a Lamborghini Huracan. Will this battery-powered bike – costing no more than $500 – beat a $250,000 car? As daylight in Utah dims, Heavy D buckles up on an 80-volt powered mini-bike putting his money where his mouth is.

The season wouldn’t be complete without a few surprises up their sleeves. In true DIESEL BROTHERS fashion, the team shows no fear of any challenge that comes their way. This season DIESEL BROTHERS will go outside their comfort-zone taking their iconic builds to the track where the stakes are higher and the competition has never been muddier.

The mud is deeper, the jumps are higher, the trucks are bigger and the Dirty 7 is ready to take things back to The Pit and prove once and for all that they’re the dirtiest Mudder Truckers around. Crews from all over the country travel down to central Florida to take on the ‘Dirty 7′ in The Pit – a 750-foot stretch of mud with tracks designed to chew up and spit out mega-trucks of every size. Only one team will be able to push each other and their machines to the limit and come out on top.

An all new season of DIRTY MUDDER TRUCKERS premieres Monday, December 9 at 9PM ET/PT on Discovery Channel. Mondays are going to be Trucking Huge as DIESEL BROTHERS leads into the new season of DIRTY MUDDER TRUCKERS for back-to-back muddy motor madness fans won’t want to miss.

In the marshes, fields and forests of central Florida, trucks have always been a way of life. Drivers put everything they have into building their mega-trucks – blood, sweat, tears and money – motivated simply by the need to prove their driving skills and find out who’s the best of the best in the racing world they’ve created. Now, teams of drivers from around the country have adopted Florida’s unique mega-truck racing style and have descended down south to take on the Dirty 7 on the muddiest, toughest track around.

This season, all of the original Dirty 7 heavy-hitters and their iconic mega-trucks are back, including Pete Eurle with “Chasin’ Paper,” Randy Priest with “Mudstick,” Keith Spiker with “Hammerhead,” and Jimmy Yeager with his truck “Steamboat.” After a successful first season, young-gun Chris Liback decides it’s time for “Animalistic” to get an upgrade and introduces “Animalistic” 2.0 during the first race of the season. But will it be able to top what his truck accomplished last year?

The trucks aren’t the only ones getting a makeover this season on DIRTY MUDDER TRUCKERS – The Pit has been remodeled to include even more mud and a new route that gives the drivers the opportunity to get to higher speeds. The newly designed split track sends the drivers down two separate long-jumps before heading into a high-speed straight away barreling towards each other, finishing out with a final jump into a giant pit of mud. Drivers who thought The Pit was tough last season are in for one high-flying muddy surprise.

Each week, reputations will be put to the test. With a total of 12 races throughout the season, unlimited side-bets and a big pot of prize money on the line, things are sure to get personal. The Dirty 7 are eager to reclaim their title as best mega-truck drivers in the game after a devastating defeat by Georgia last season – but will the team be able to rally together and put their skills to the test on the most challenging proving grounds to-date?

The season wouldn’t be complete without the Dirty 7 pushing themselves outside their comfort zone. This season, the fearless team answers a call viewers won’t expect in what could become a race of firsts for two very different teams. It’s the finale event Discovery motor fans won’t want to miss.
