I solo hookup 100% of the time... IF you do not want to go to the expense of a back up camera (well worth the $$$) here is what I used to do.. On the center of your tailgate put a bit of tape or better still a paint marking you can see.. then on the RV do the same (when you are hooked up) make sure the 2 line up after that when backing in just match the 2 marks and you will always be right on the money... the marks have to be just big enough that you can see them from the cab.. I tried the magnetic balls on a stick and found this worked better.. You can disguise the mark on the trailer with a small decal of some kind.. just use the tape first so you are right on then apply the decal.
