Ok so I bought my 2016 Expedition EL Platnium used and didn't pay much attention to the tow package as I didnt have any intentions of towing. Now the wife really wants a camper, as do I, and I'm finding two different towing capacities based on whether or not I have the "HD" tow package. My expedition has built in electric trailer brake, the hitch, a 4 pin and 7 prong plug, as well as setting tan in the dash board infotainment center that I can select for towing option and trailer connect and such. Can anyone tell me if that indicates an HD package? Or is there something I can look for? Axle code is 3L.
