Owning multiple properties and flying between them is something rich people do that wastes an astronomical amount of resources, and the fact that it wastes more than towing 13,000lbs of RV around doesn't make either of them any better.
Or any worse - you apparently didn't notice, but I wrote that there are good reasons to own an RV, and want to reiterate that. Probably in your heart of hearts you know whether your ownership is justified, and I don't need to tell you.
TONs of non-rich people also have 2 properties and go between them. You can buy a cabin or vacation property in the rural US for a surprisingly affordable amount. I know many folks who are certainly not rich, but do spend time in various locations.
Think traveling nurses, seasonal employees, etc. Also look up the term "snow bird"
