I am a single woman RVer. First, I bought a very used but reliable coach; then I make sure to keep it maintained so that I am less likely to break down; next I read all of my manuals and learned how to do very basic stuff (like change a fuse); then I put together a small toolbox that I carry with me always (I made up my toolbox from a list that I found on this forum); last...I read forums constantly to learn more about how to trouble shoot problems on my rig. Oh yes, like Ned mentioned, I purchased a good road side service plan.
I am pretty new at this, but so far, everything has worked out just great. I lost all power while boondocking over labor day and was able to find the source of the problem and fix it pretty quickly. I never boondock alone, and actually discussed the issue with several of my neighbors before I found the solution. People are very helpful, especially when they see you outside staring at your rig and scratching your head in confusion! They will come right over to see what the problem is.
Backing into really tight spaces can also be another challenge. One space that I had to squeeze into over the summer had a big palm tree right in the middle of the campsite at the entrance. I was backing my 32' Class A into it from a very small camp road that did not give me much wiggle room. All of my neighbors ended up coming out to help, and after much pulling forward, turning, and inching back, I was finally in. Like I said, folks are pretty eager to help when they see you are in a jam.
Hope this was helpful too. Have fun!!
