2019 ram 5th gen quad cab Bighorn 4x4 5.7 torque air suspension locking rear diff off road pack level 2 rugged brown with tan /black.I bought quad cab so it would fit in the garage, I also carry a 50 inchRZR in the back while pulling a 22' camper. Camperweight weight is 5000lbs loaded 500 hitch weight and RZR wt is 1200lbs so truck is working when we go on a trip. I live in Colorado so I regularly go over 1200' passes and am happy to report truck will do these passes and grades without giving it much thought. Really had a hard time on deciding on gear ratio and selected the 3:21. I have had truck for 1year no issues what so ever and have extras like rock sliders and fender flares
