I just purchased my dream truck a new GMC 3500HD Duramax as i prepare to to become a frequent traveling RVer. The truck I bought came with the new GM 5th wheel / goose neck under box towing prevision which was designed in partnership with curt. Since the truck is a 6 1/2 box I knew I would want to get a slider type hitch as an insurance policy. The issue I just learned is the mount is designed to on accept the Curt legs and "fixed" hitch. (no one else makes anything yet) They are still in development for their roller/slider product. So I'm at a loss for options... what about a sidewinder type pin box (pros/cons?) other options? I'm planning to get a new Keystone toyhauler (raptor or fuzion) so I know they have the rounded nose which may minimize my risk. Any Help? Opinions? Thanks
