Ready to confirm my order, but does anyone know the tongue weight of the 2" accessory hitch? I have a rather heavy Thule bike rack and with 3 bikes the weight is 160+ pounds. The X owners manual still lists the 1.25" hitch with its 120 pound restriction. The tow package hitch will work but I really don't have a need for it. Is the accessory hitch the same as that on the tow package except without the wiring?
