With the 1500 RAMs, one can order a Trailer Tow Group, or a Trailer Hitch and Trailer-Brake kit separately. However, when I use the NADA build site for 2022 2500 RAMs, there is no Trailer package, nor is there a separate Trailer Hitch and/or Trailer-Brake kit offered. There is a Trailer-Technology Group but it's just full of cameras, mirrors and other stuff I don't want. Am I missing something? Or do folks buy and install hitches and trailer-brake kits as aftermarket products?
