I used to have a Bronco. It was my first vehicle and the 302 got about 9.5 mpg, but the fuel injectors leaked. Then the Borg Warner transfer case went out while I was at about a 60 degree angle and I decided to sell it. Phoenix, you must be thinking of the Bronco II which is pretty narrow, because the Bronco is pretty wide.

In any case, my next off-roading truck will be a Kaiser-Jeep M715.
