Just a heads-up on the flat folding rear floor for the Gen 4 Quad Cab. I've been told that I need a Gen 4 (2009-present) in order for it to fit. Wrong. I just bought one from a 2003 or 2004 Ram and it bolts right into the existing holes of my 2017. $35 at the local junk yard. It would have been a 10 minute install except it takes an 18mm socket and I had to go buy one. What an odd size.
