I have been solo forever because I started my RV experience after my wife died. I wanted to take my/her dog along to Alaska.
First was the Fun Finder shortly replaced with the Arctic Fox TT for the Alaska trip. Never pulled a trailer. But I learned. Not a big thing after a while. The thing I learned was to trust my mirrors and get out and look while backing in. To this day I still get out and look. Even with the class A and now the class C. Well I did hit a tree that ran behind my first class C on its first trip.
To be solo the hardest thing is to predict where you are going to stop for the night. Or finding your way through cities you do not know. I am finding a GPS to be helpful in cities.
I normally take a break at noon and call ahead to find out if there is a sight open in the range of how far I want to go for the day. If not then I call till I find a spot open and get there.
Now days with the TV backup cameras. If it was not so much work for an old guy. I would go back to a TT. But nothing beats pulling in and just getting out of the drives seat and turning around with the feeling of being home for the night or more.
