Dev's Show and Shine 2025

Sat, August 2, 2025, 9:41 am

We are hosting the Second Annual Devin Anthony Mansen (DAM) Memorial Show and Shine Diesel Truck Show, taking place on Saturday, August 2nd, 2025, at Penngrove Park in Penngrove, CA. This event is a celebration of Devin’s passion for diesel trucks and a way to bring together a community that meant so much to him. With the help of the community, we hope to make this event a sell-out success.

For our sponsors, we offer Bronze, Silver, and Gold tiers (details below). This year’s event will feature music, food trucks—including Galvan’s Eatery—and a gathering of diesel truck enthusiasts, family, and friends.

Why sponsor this show? FOR THE LOVE OF DEVIN!

Your generous contribution, in any amount, will help us celebrate and honor the life of Devin Mansen (22), a passionate diesel truck enthusiast and beloved member of our community.

Born and raised in Rohnert Park, CA, Devin was a 2018 graduate of Cardinal Newman High School, where he played football all four years. After graduation, he worked locally—first at RC Cabinets & Closets, then at Tight Access Excavation, where he pursued his dream of obtaining his Class A license, earning him the nickname “Heavy Haul Dev.”

From a young age, Devin was passionate about diesel engines and trucks, which was heavily influenced by his close family and friends in the diesel truck community. He spent countless hours building a one-of-a-kind truck using his self-taught mechanical skills. In 2019, he entered his first truck show, proudly showcasing his 2002 Chevy 2500 Duramax. He continued to display his truck in the following years, furthering his dream of becoming a respected figure in the diesel truck event community. With your support, we can honor Devin’s memory and help keep that dream alive.

Beyond celebrating Devin’s passion, this event is about helping others—just as Devin always did. Proceeds from this event will go toward a 501c3 fund created in Devin’s honor to support local families experiencing a tragedy. Each year, we will support one or two families by providing financial assistance for urgent needs such as medical bills, funeral expenses, and meals. Devin was always quick to lend a helping hand, and through this fund, we hope to continue his legacy by offering the same support to others during their toughest times.

We deeply appreciate your consideration and look forward to partnering with you for this special event. If you would like to sponsor,  please view our website and click the http://www.damshowandshine.com/  Sponsorship Opportunities link.  Please kindly note that all donations are tax deductible.
