I own a 2014 Ram 2500 4x4 with Rambox storage system. I purchased truck with the intent to purchase a fifth wheel toy hauler. I did a little research prior to purchasing and was told that Reese sidewinder would allow my truck to tow a fifth wheeler. Now being told that Lippert will have issue with the Reese Sidewinder pin box. Problem is that Lippert seams to be making all toy hauler frames. Have found that Forest River Flagstaff fifth wheels come with the Reese Revaluation (a Reese Sidewinder, but put on at the factory), but this will not allow me to carry my toys. I'm looking at getting an Edge ED 386, and was wondering if anyone had experience with the Reese sidewinder pin box with this fifth wheeler. Anyone using a Reese Revolution/Sidewinder with a toy hauler? Anyone had problems or caused damage to fifth wheel due to Reese Revolution/Sidewinder
