Hi, Ethel, I'm new here as well, and new to solo RVing, but not picking out RVs.
I have an almost 30 foot class A, my first class A (though I've owned a fifth wheel and a class C), and I was/and still am sometimes scared to drive it. It feels big, but from the side it looks kind of small (for living in). The front dash is big, and I know that many gals prefer the smaller cockpits as in class C's or the Roadtrek's. I often wished that I had bought one of those, so I could just "take off" and buzz down the road without worrying about whether my rig is between the lines. I find the more I drive it, the less I worry about being between the lines because I get the feel for the size of it. It's actually kind of neat to look out over the traffic, though I still struggle with depth perception behind me. If you haven't attended an RV driving class, and can't get to one, there is a series of videos online from the RV Driver Confidence Course that I found SUPER helpful regarding anything from adjusting mirrors to turning radius, backing in, reference points, etc. Here's the link to the first one, and you can find the rest from there.

I do have some buyer's remorse myself, thinking I should have gotten a rig "closer to the ground" or a better quality, or maybe even bigger (longer). Even 30 feet can feel like a scrunch if someone is traveling with you or you have animals. Our last fifth wheel was 37 feet (3 slides), but my S/O drove that one primarily. That was actually good living!
I do get worried when I don't drive it, and the anxiety builds again, so I think I just need to keep driving it. That might be the case for you.
Weather wise, like everyone said, Florida, Arizona, Texas. Though they have all experienced cold temps so far this fall. I personally love the Gulf Coast of Alabama, spent several winters there in an RV (not solo).
But it's truly up to you what you want to do. If I really, really hated it, and could afford to have quite a bit of money added onto the next RV I purchase (being upside down on the loan), then I would trade it in, consign it, etc. Like a car, it's hard to trade in for something less expensive (smaller) though. And make the salespeople give you some lessons on driving the rig. They will. By the way, my S/O measured the front of my 30 foot class A. He said a class C was several inches wider. Hmmm...
Good luck with your decision and let us know how it goes.
And P.S., I just noticed one RV park advertised an RV valet. Oh, yes, please!!
