The truck is a 2006 Dodge Ram 3500 Dually. It has the 5.9L diesel Cummins motor. It has the Big Hoss Bundle from Banks ($3500 kit) installed, that an exhaust, intake, 6 gun tuner, and a huge intercooler, (probably forgot something). My question is, does anyone know where to find the gear ratio, and if you think this is enough to haul a 2007 Keystone Raptor 3612 with 2 slides??
