as said above, tailgate issues. rusting out, window motors are always bad, window tracks break/the steel they are mounted to rusts away, wont latch down, defrosters dont work, pretty much anything in the tailgate is usually crap.
the core supports on that era fords are always bad. there are a few different fixes for them, usually have to get a bit creative, as new ones are expensive and will be bad in a matter of a few years.
for some reason, the doors tend to hit the fenders when opening and chip paint/bend the door. not sure on the exact reason for this.
