If I was ever by myself, I'm not sure I'd want to camp. I've been RV'ing for over 20 years with the family. I've been married almost 30 years so I can't imagine what I'd do by myself, period. I'm sure my wife will outlive me by quite a few years so it won't matter. ;)
Regarding the logistics, I always hook up by myself. I just back up a few feet at a time until I get the ball in place. My wife is useless trying to assist with hooking up or backing me into a site. She gets so flustered by the process that it just stresses her out. Even when she tries, I can't hear or see her well enough to be of any help. I should buy one of the backup mirrors.
