I've spent 6 of the past 7 years living in an RV (motorhome first, now an old Avion travel trailer with a big old truck to tow it). I recommend it for anyone who is unencumbered enough of other people and responsibilities to do so (i.e., it may not be the right thing for a family with kids, though I know some families with kids who do it and seem happy).
The freedom to travel is magnificent. It precludes many kinds of opportunities, but if you can work remotely, why not do it at the beach or in the mountains or in the desert or wherever you like? It's not dramatically less expensive than living in fixed housing (though that depends on where you were living in the house and where you're parking your RV; when I first started I moved out of a tiny rental house in Mountain View, CA, which cost $2145/month, so I'm not spending anywhere near that now), or at least it hasn't been for me, but there are many benefits outside of cost.
I wouldn't, but I know a number of people who do. Or, people who have a toilet, but don't use it because they park off-the-grid for long periods of time. It's do-able.
When I've wanted to live in cities without a nearby RV park, I have been known to use a gym for shower/toilet (when I was moving around a lot more often than I do now, I had an all-club membership at 24 Hour Fitness; Planet Fitness is a better deal now, but they have a lot fewer clubs), so I could extend my time between driving to a dump station.
