Those concerned about fitting things in a short bed need not worry, as the Tarok has a trick up its sleeve. Instead of treating the bed and cab as separate entities, the Tarok has a panel that can open up and extend the bed into the cab, allowing the truck to fit items that are up to 73.2 inches long. Open the tailgate and you get another 25.8 inches, but then you also lose the backstop that the tailgate normally provides. On the whole, it can handle 2,271 pounds of payload. The rear panel locks electronically from the inside, so people shouldn't be sneaking into your truck.

Whereas the Atlas Tanoak had a design flourish that sort of made it appear like a body-on-frame pickup, the Tarok has no qualms about wearing its unibody construction on its sleeve.
