September 26–27, 2026 · Fairplex, Pomona, California
Pomona remains one of Southern California's most recognizable meeting points for custom automotive culture, and the Grand National Truck Show puts custom trucks, builders, vendors and specialty work at the center of that scene for a full weekend at Fairplex.
For LA Calendar Girls, the value is not only the finished trucks on display. It is the concentration of builders, fabricators, shops, parts companies, painters, photographers, vendors, owners and works in progress that reveal how the custom-truck world is actually built.
