12: Jeep J6
When Jeep announced the Gladiator pickup truck enthusiasts were very pleased. It was the Jeep truck of their dreams, wrapped up in a non-compromised package. But there was a catch, and that was that it didn’t come in a single cab configuration. The J6 was sort of a cruel trick that let a lot of traditional Jeep enthusiasts down. They had hoped for a modern version of the Commanche pickup truck and instead were greeted by this concept.

Indeed, the modern pickup truck market doesn’t favor single cab trucks and the best you can get is an extended cab. Still, the J6 was an interesting concept that seemed to be production-ready which left a lot of drivers scratching their heads. Why would Jeep release a production-ready concept only to let an entire segment down?
