Ford sells Ranger single cabs; just not in North America.
Physics says that if you design a 4/5 passenger truck with 5' bed on 4 wheels with mandated crumple zones, it is going to be Honda Ridgeline/Ford Ranger/Toyota Tacoma size. Does Hyundai really think they can sell a mid size pickup? (Hint: Honda only sold 50k in its best year, new model is barely selling 30k)
I was hoping for 'halo' vehicle in Santa Cruz - a Mazda Miata. 2 seats (maybe some sort of 3rd jump seat), small box, light towing. Sell 10k/yr to enthusiasts, but more to get foot traffic into dealership to sell the bread and butter.
A unibody clone pickup isn't going to sell 30k /yr; there's too much competition now and Hyundai doesn't have a "name" for that market. So, if its going to be small volume; make it attractive to that niche market.
