I get out and look for myself and visualize the needed track for my inside trailer wheels, I drop a stack of plastic blocks where I want my wheel to end up, get back in the truck and follow that visual in my head until my closest inside wheel is in position. My wife gets out and her only instruction is yell stop if I am about to hit something. But there is never anything to hit. Most of backing issues are taken care of by driving your rig forward to the proper starting point. Most people look at the whole trailer, I look at one wheel. I know how big, how wide I am so I know that my wheel has to track where I want it to track. If I lose my image of what I am doing I get back out and replace it in my head.
