some it comes easy.. others never get it.
and most are somewhere in between.
this past spring.. I had to backup my 30 foot travel trailer uphill for more then a 1,000 feet on gravel. with drainage ditches 18 inches on each side.. did it on the first try. go SLOW and catch it early. and keep your eyes on the rear most vertical edge of trailer. as soon as you loose sight of it.. correct.
but then I have pulled/backup almost everything possible with a tow truck. when you learn to backup a dead truck into a service bay and onto a LIFT........
