I have a 2011 Ram, quadcab, hemi, 3.55 gears, 20-inch wheels. I recently purchased a Keystone Passport 31RE which has about the same weights as your trailer. I purchased an Equalizer WDH and installed Airlift 1000 airbags in the coil springs. I also purchased the OEM brake controller that I installed in about 10 minutes. My first tow experience was a 5 hour drive home doing 60-70mph on the interstate. The HEMI rocks!! You did know the trailer was behind you but I think any truck would be the same way with that length. I had no problems with braking or sway from passing semis or me passing them. Without running out to my truck to look on the sticker, I remember the payload being like 1420lbs. Get a good WDH and you should have no problems.
