Hi everyone. Hopefully this hasn't been posted before. I did look. Anyway I just purchased my Laramie as above and the Options Sheet the dealer fave me ahows "AHC Trailer Tow Group". Can someone please tell me what all is included in that? The dealer checked the VIN for me and said it is rated for 8500#. It has 3.92 gears and 20" tires so is that the correct weight? Also, what else does the Tow Group contain? (Tranny cooler? Wiring for brake controller etcetera?) I meant to ask the dealer but I was kinda falling in love with the truck and forgot to ask.
