Well I bit the bullet and traded my 2011 Ram 3500HD SRW in for a 2012 Ram 3500HD dual rear wheel. The SRW did the job of towing my 36RL, but I felt the truck worked too hard to haul the load that was being placed on the drive train/suspension/tires. I had the truck dealer remove my Pullrite Super 5th 20.5k hitch and reinstall into my new truck. My question is to any of you that have a Ram dually: have you found that the slightly taller height of the bed rails due to the dually created any issues for you getting under your Redwood? I have the Trail Air Rota - Flex hitch and dont expect any issues, but I did notice that the top of the tailgate is taller than what my single rear wheel was.
