Mikleton, the best advise for new trailer owner is to take your time with everything.
Prior to hitting the highway you should become familiar with the "LOOK" through the mirrors, of your overall length.
A little time in an open parking area off in a corner of a big shopping center will help you become more familiar with the turning radius of the rig.
Begin your backing education in a straight line. Learn to back straight. Small corrections and pulling forward to straighten out are key.
Once on the open road the simple lesson of all driving instruction is to, "look ahead and drive there."
Best of luck on your maiden voyage.
