I called (!) to see if the truck was done, picked it up (all while Ammon used the air compresser to pump up the trailer tire as a temporary measure), Adria and Ammon backed me into the hitch, and Ammon and Tanner helped me back into the driveway. No stress. It isn't straight, but works, and I figure with some practice it could be straighter. Admittedly Stephen asked about whether I jack-knifed the truck, and I may have, but there was no damage to his bumper which he said was why that shouldn't be done, so I learned something knew.
Anyway, I am feeling kind of empowered at the moment.
Book recommendation :

Stick through it, you'll see what I mean.
