Overlanding has been taking over the off-road scene in the past few years, and Ram is capitalizing on the trend with its concept for next week's SEMA show. Called the Ram 1500 Rebel OTG -- OTG stands for Off The Grid -- this Ram has been designed to "allow vehicle-supported, self-reliant adventure travel," according to Joe Dehner, head of Ram Truck and Mopar design. The Rebel OTG has been created with a mix of concept parts, purchasable Mopar accessories, and items produced by outdoor equipment companies.
