Pretty much nobody offers a stick these days in trucks; they've been gone from half-tons for about a decade now. The Bronco is unique among Ford trucks in being offered with a manual transmission.Manual transmissions in trucks are "old technology" and rarely if ever will you see them anymore. Autos have a higher tow rating and better mpg. Ford super duty doesn't offer a manual with either the gas or diesel engines.
It sucks, but that's the way it is.
