The only cool part about a “King Raptor” would be the ability to get a 2 tone paint job and painted fender flares instead of the god awful colored plastic we get. Color matching Front and rear bumpers could be interesting too, oh and the snake on the center console with sadddle / dark brown as an interior color option.
Aside from this (mainly cosmetic and color options) the Raptor is just as luxurious as a King Ranch, so doesn’t really make much sense. Would be more of an appearance package more than anything (kind of like sport vs chrome on the XLT).
