Dave Sparks is an American entrepreneur, custom vehicle builder, and social media personality from Salt Lake City, Utah. He goes by the name Heavy D. Since he was little, Dave has been fascinated by anything with an engine or wheels. From his first motorcycle, a 1976 Yamaha YZ80 to his most famous creation, the Mega Ram Runner, he has always pushed the mechanical limits of vehicles. Dave spent the majority of his time in high school studying auto mechanics, welding, and fabrication. After high school he managed an ATV and motorcycle rental business for his close friend and mentor, Rich Eggett. This allowed him to obtain countless hours of hands-on experience. At age 21, Dave enrolled in college at Weber State University; but, after one semester he determined he could learn better on his own with real-world experience than in a classroom. Dave began operating heavy equipment for his uncle's construction business, which soon turned into Dave running his own small excavation business building rock walls, waterfalls, and other types of landscaping. In 2008, he hired his first employee, his best friend "Diesel Dave" Kiley, to help him run the equipment. In 2009, Dave met the girl of his dreams at church and married her one year later. Once married, he picked up his dealers license, opened a small used car lot, and started working to build his dream company, DieselSellerz.com. His business has grown and so has his family -- he has two adorable kids.

The first time Diesel Dave met Heavy D, they were at a church event for young singles and Heavy D invited Diesel to the lake with friends in his pickup. Knowing that diesel trucks, boats, and lakes are the perfect recipe for wooing single ladies, Diesel accepted the invitation; but, little did he know that this would lead to a successful career in selling and building diesel trucks. After Heavy D accidentally put gasoline in his new pickup truck, Diesel Dave came to the rescue and helped syphon the tank. It was over the syphoning of gasoline at a fuel station that the Daves bonded over their love of diesel trucks and where they decided to start up DieselSellerz. DieselSellerz is a haven for diesel fanatics everywhere. Building and selling diesel trucks at DieselSellerz, diesel passion runs rich in Diesel Dave's blood. He wants nothing more than to put the hammer down and spread torque, horsepower, and diesel joy to all people through the land -- letting Diesel freedom ring!

Money Man Red Beard grew up in the small town of Roosevelt, UT, in an area known as the Uintah Basin which is part of a Ute Indian reservation. In the Uintah Basin, diesel truly is king. Everybody drove a diesel, and if you didn't, you wish you did -- diesel trucks are just part of the culture. Red Beard met Diesel Dave through a mutual group of friends several years before DieselSellerz existed. He had heard of Heavy D through the same group of friends but they hadn't ever met. Red Beard had built and sold several businesses by the time Heavy D started DieselSellerz. When the company started to take off, Heavy D began looking for a business savvy chap like Redbeard to help organize and grow the business. An introduction was made and the rest as they say is history. Red Beard says that his greatest accomplishment, though, was "talking a super hot, amazing woman into marrying me. I also got 4 crazy cool kids out of the deal."

The Muscle grew up in Utah, and says that his greatest loves are "football, diesel trucks, God, my family and this great country." He has known Diesel Dave since they first met in the 8th grade, and they have been friends ever since. The master at finding rare parts, The Muscle comes from a family of diesel fanatics. The second he drove a diesel truck he fell in love and has been building them ever since. He met Heavy D a few years ago through friends and decided to join him and Redbeard on "this crazy journey into the diesel world." They are not only in business together, but they are also great friends. In addition to his work at DieselSellerz, The Muscle has been in the fitness industry for as long as he can remember. He has been a personal trainer to over 2,500 people, and loves to help people achieve their fitness goals. He credits his late father with teaching him how to work hard and work smart. The Muscle is proud of his business successes, but even prouder of "my beautiful wife and two beautiful daughters." Known for his strong opinions and drive, he says that he lives by one motto: :you can have or do anything you want in life if you put your mind to it."
