One pilgrimage we take each year is the annual SEMA show, in Las Vegas, Nevada. For an entire week, buyers, sellers, dealers, and builders crash the Las Vegas Convention Center for a whirlwind of aftermarket performance. For us, it was all about compression ignition, of course, but diesels seemed to be a hot theme at the show as well. There was an entire section of trucks on display, and many off-road fabricators, show truck builders, and performance enthusiasts chose diesels as platforms to show off their skills. We literally walked for miles, taking everything in—all to bring to you the best of what the 2012 SEMA show had to offer.
