There's an excellent trick if you must do a lot of this.  Fit a second tow
ball on the FRONT of the tow vehicle.  Pull up in the general area, flip
the tow vehicle around, and hey presto, not only can you see what you're
doing, but the steerable wheels are under the towball, AND they do things
you expect 'em to do.   Done by professional mobile home movers on occasion
- lets you spot the trailer to within fractions of an inch with ease (given
practice, of course.)

"Backing up" the trailer looses its terrors quicksmart.
