Sent you PM. That Ram should be good. My 2013 2500 tows my 2016 27RK like it's not even there (except you know it is when you start and tow uphill). I use a 6.0 gain on my brake controller and it's smooth and steady. Tow haul mode and EB on full and the only time I use the brakes is when someone in front of me is. Downhills are a breeze, the EB and engine/trans do most of the work keeping me under control. braking is always a minimum (as long as you pay attention to the curve signs)
Sorry didn't get your PM until today, was in Yellowstone for a week, just got back.
