True duels are tough on a Bronco. Between the short wheelbace, trans/transfer case, and the huge rear tank...there just is not a ton of room. Ya, it could be done, and has been, but probably would not be a big seller. Add to that, with the window down, or the top off, your going to get gassed out, and that off road, a single, side outlet is just better. Less to get knocked off.
