Yes, the previous posts are good advice. I would toss in a suggestion on checking with Tom Johnson's RV in Marion, NC, since you are in NC already.
The concerns about the size of the rig are valid, of course, but not the whole story. Except for class B units, they are all the same width. Longer, maybe, but the stuff behind you just follows along, whether it's 25 feet or 45 feet. You just drive it and the rest of it gets there too. True, parking can be tricky, but you can practice that.
Get the coach you want. If you can rent or borrow, you can take some baby steps, but if you want to do this, just go for it.
