Thanks, I've got my dealer working on getting me an estimate now, but I'm not sure they can/will do it all? Has anyone done this through a dealer before?
I'd like to have all OEM parts so that it truly does have the factory HD tow package. The parts that I know of include the HD radiator, aux tranny cooler, 'heavy duty' flashers (whatever that is...is this just a relay or is it new blinker bulbs at all 4 corners?), electronic brake controller (where does this go on a 2014?) and wiring harness change to include the 7-pin connector and the 4-pin trailer connector.
My class IV factory hitch with 4-pin connector is the same as would be included in the HD tow package from what I can tell. It says it's rated for towing up to 9200 lbs on a sticker on it.
