The problem with most alignment gimmicks is you’re not looking in your mirrors... which is the problem in the first place.
pretty much this.
I lineup small highway cones with the happijacs about 20' in front of the camper. That allows me to use my mirrors to line up straight and square to the camper. Then it's relatively easy to back it in using only the mirrors and fisheyes to see the cones. I usually jump out a couple of times as I get close to check and see if anything's scraping. Have only ever loaded it by myself and have not had a problem.
