I can imagine a scenario like the following... you own a nice piece of private varnish, or better still, two cars ... you own your own siding, so you're not paying a string of short-term storage fees at your "home base" ... you're friends with some handy maintenance people who will trade work for occasional luxury trips ... and you don't mind spending at least half your time dressed in a snappy conductor's uniform playing host to high-paying customers, to subsidize your occasional private jaunts around the country.
I've actually contemplated this for myself, though I haven't worked out the economics to see if it's actually viable. It would probably require start-up capital of $100-250,000, at a very rough guess. But if you're a homeowner, and you're actually selling your home to do this whole hog?... it might work?...
This certainly happens in song:
"Railroad Bill, Railroad Bill, he never worked and he never will, he'll just ride, ride, ride..." Not such a bad outcome for Bill...
"Did he ever return, no he never returned -- and his fate is still unlearned! Poor old Charlie..." Didn't work out so well for Charlie, on the other hand! Free sandwiches, though :lol:
