We have a very different methodology.
Her job is that of safety observer only. Looking eveywhere at once, seeing any danger. Job #1 and only, don't let me hit anything or do any damage. The truck windows are down, she has a definate responsibility to start screaming and arm waving BEFORE any sheet metal gets bent.
My job is placement. I get out look the site over and decide where I want the port aft corner and port forward corner, to get hook ups right. These 2 spots are marked with a rag during daylite hours and a flashlite at night. Pull up slightly past center with the site to port, get the initial angle, and put her in the hole. If the site is to starboard, the same procedure applies, its just a little more difficult seeing the starbord corner markings in the mirrors. Never any discourse or problem, no damages, and usually only one or two pull ups required.
