Toyota Tundra Heavy-Duty Dualie Diesel

(WARNING! DISCLAIMER ALERT! We want to be clear right up front. Toyota wants to make sure we don't accidentally misunderstand what it means when it commissions a special project like this. In fact, it doesn't even want us to use the word "concept" because as anyone who's been to an auto show knows, what's shown as a concept often becomes reality a few years later. As we understand it, this custom project is just a one-off physical expression from a mad scientist. Yeah, right.)
