I bought a F250 diesel to tow my 13,000 lb rv. Smaller vehicles can't do that.
There are obviously some good reasons to buy a huge RV instead of using a tent, but the RV itself is an expensive and heavy status symbol.
We live in our RV for 3-6 months a year, in weather from -10 in Colorado blizzards and 120 degree California summers. In rain snow and sleet. I work remotely from it.
A tent is not a home. An RV It is for many of us.
Before you throw more stones, it's far more eco friendly and lower carbon Footprint to own an rv and travel and stay in it in various places than to own several properties and fly between them.
It's considered worse to drive (vs fly) unless you have more than 2 people-- and that's for a normal car. With a truck+trailer the break-even point would need more passengers.

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.
