Yeah I don't think that Ford even makes a 2-seater anymore in anything other than their XL/fleet model. You can buy the "extended cab" in the XLT (the base trim sold to consumers), which is the 2 seater with a small bench in the back, but even those are really hard to find, you don't see them often.

But after you get above the base model, the only thing available is "crew cabs" which is the full 4-seat SUV size interior.

Really trucks have become 4 seat vehicles now. The super-crew (4 seat) cabs are essentially standard at dealerships. The only way to get a 2 seater truck is by buying one through a fleet program. And right now that would be essentially impossible. Trucks are hard to get right now and most dealerships won't sell a fleet vehicle to a consumer because the demand for fleet trucks is too high right now.
