Backing tips please

One of the most challenging places has been Haverty's furniture in Springfield, Missouri. It is a small and tight lot with a brick wall and drop off at the end. I had to jackknife the trailer against the door. Only took two tries (toot my own horn, but I was lucky that day and wish I had a video of what I did, cause I will probably never do it again) but set it right against the receiving door with the tractor at a 90 degree angle.

Today, after being off the road for two weeks for the holidays, took me three pull ups to get into a spot at the J, and two pull ups at the receivers in greensburg, PA.
