I drive a silver Shorbed single cab Chevy thats owned by my employer, its a '14, but we also have a '17. I was given a seat in the '17 if I wanted it, I declined. That one is the 6cyl. the 14' I drive is the 5.3, and plenty of pep in a small package
We also have a Sierra in similar configuration, older body, a 2012
They are out there, and I have seen several of the "current generation" rams that are short bed single cabs, but dont ever see fords in that configuration....
According to Ford's website, they do sell short single cabs, i just dont see em.
here is a GM photo
