I own a 2019 F150 Supercrew 3.5L with 3.55 Axle & 145 wheel base. When looking at Ford specs for Tow Capacity and 5th-Wheel Capacity there was a note (1) on 5th Wheel section "Vehicles equipped with 5.5 box will accept a 5th-wheel hitch, but current 5th-wheel trailer designs are not compatiable with this model (145" wheel base super crew)." Since I just bought the vehicle and am in the market for a light-weight 5th-wheel how do I get information on what the issue is? I don't want to ask any RV dealership so should I query manufacturers or where at Ford can I direct my question? Thank You.
