Got a recall on December 15, 2017 about the second gas tank issue. Advised not to fill the second tank because it cause the front tank to expand, rub the drive shaft, and cause a leak and possible fire. They said that they would notify when parts are available. Have not heard anything back yet. It has been 2 months. We travel long distances with this truck and need the added fuel from the second tank. Thank you
