the closer the wheels of the trailer to the hitch point the more difficult it is to back a trailer up. open the rear hatch and drop the rear seats for better visibility. as Colson79 posted practice, also look up on line trailer backing technique. there is an art to it and we that have many years of practice it's not that hard to do.
a few years ago i built a 40" bar extension out of some 2" square tube for towing my jet ski. it made it so much easier to back it into the tight spot i had in my garage for it. heck where in fl are you i dont have a need for it anymore if you'd care to buy it. pm an emaila ddy and ill send you a pick of it hooked to my X3 with the ski hitched up.
