I don't see the attraction but when you consider all the overhead costs that come with living traditionally I can see why it makes sense.

FWIW a non-trivial minority of people in the residential building trades have been doing this for years. They move north and south with the construction seasons.

That overhead comes with quality of life.

As a nomad in an RV you don't have a fridge, a shower and the price of the RV loses value over time compared to a house.

No nesccesarily, the options are more broad than just an RV for sure, if you can earn an income remotely you have far better options. For example in germany a huge percentage of the population rent rather than buy : http://www.rentalcal.eu/the-german-rental-market There are good regulations around it there, but there is not the drive to own. Again though it's different folks different strokes.
