I had a conversation with Ranch and ended up putting 9000's on the back and 5000's on the front of a 2015 Ram dually (exact same suspension you are using).
IT WAS A MESS. I could hit dips in the road at 45mph that would start the rear of the truck osculating and only thing that would stop it was to slow down.
Rancho sent me new 9000's which did nothing to stop the problem. Ended up sending all 4 socks back to Rancho (they have this test drive problem) and going with Biletein 4300's.
Later I got the 2018 which I left stock.
If you were loaded all the time I would suggest going to FOX shocks and have them valved for the weight. I put a set on my Sprinter MH that were valved by Agile Offroad (who also owned a Sprinter MH) and it made a world of difference in both ride AND body sway.
