The Great American Trucking Show

Each August, some 30,000 people descend upon Dallas for the Great American Trucking Show. The three-day event entails industry panels, driver recruiting forums, rows of vendors with new trucking products, and perhaps most spectacularly, rows of glittering big rigs polished to perfection for one of the largest truck beauty pageants in the U.S.

You heard right: a truck beauty pageant. In the annual Overdrive's Pride & Polish championship, dozens of jaw-dropping show trucks compete for cash prizes and bragging rights. Owners pour hundreds of thousands of dollars into custom paint jobs, intricately detailed interiors, high-end sound systems and over-the-top chrome finishes. Some have even added unusual features like, in one semi truck, a stripper pole.

Some competing trucks are actual working machines; many more have been designed specifically to compete—what owners of some working rigs refer to as "trailer queens."
