If the OEM brake controller doesn't work I'm sure an aftermarket one can be installed to fill that need.I'll have to check with the brake controller. I understand I would still have the 6,000 lb limit but that's not an issue. still have a 1/2 and 3/4 ton truck for heavy loads. Would just like the ability to pull the boat or small trailers around and only take one vehicle.
Though I didn't mention this directly above, there very well may be other improvements made for the HD tow package that aren't listed and that you really wouldn't know unless you could compare the bill of materials for each build. Just throwing that out there for others who may read this thread.
