Info Needed to Pick Out Rails for Fifth Wheel Brackets in Bed of 2017 Ram 3500

Question:

Hello. Im a customer and fan of eTrailer and I need some help so I buy the correct 5th wheel bed rails. I recently bought a 2017 RAM 3500. It does not currently have bed rails, but there are holes in the bed and I see mounting brackets beneath, lined up with the holes. Looking carefully at the bed it appears there used to be two rails mounted horizontally about 22 inches apart center to center. Each rail has two rows of holes, and the rows are 4 12 apart on center. On each rail, the row closed to the tailgate has three holes one on each end, the 3rd in the center and the row closest to the cab has two at each end Is this enough for you to tell me what rails I need to buy? Thanks in advance! - Jeff

Hey Jeff, thanks for all of the info on whats in your truck bed! So you had a set of industry standard above bed rails in your truck based on all of that but we need to find out what brand of brackets you have in order to determine what rails can attach to them. Hopefully there is a brand listed on the brackets but if not there's still hope. Check out the link I attached down below and scroll through all of the picture of hitches and see if the brackets match what you see in any of the pictures. Or you can email me pictures of the brackets and I'd be able to ID them. My email is [email protected]

Hey Jeff, were you able to identify the brand of the brackets under your Ram’s bed? Knowing that would make it easier to match the right 5th wheel rails. Your update could help others trying to figure out the same setup.
