Thinking about an SUV as a home + solar powered energy for heating (2022.03.17)

I am thinking more and more about buying and living in a SUV to avoid having to pay rent and regular monthly bills. I have seen some people on YouTube, who do this.

My current detailed plan for the next winter:
An SUV, solar panel/panels, battery/batteries, charging controller, inverter (12V <> 230V), and some kind of electric heater. Preferably a low cost, small, low energy consuming heater. Theoretically I do not need a huge heater to heat the back of an SUV, where I would mostly stay, including sleeping.

If one battery would drain, then I could use another one, while the solar panel/panels would charge the other. Or I could use multiple simultaneously.

Theoretically this would lead to (close to) free living. Probably the batteries need a replacement from time to time, but no other serious expenses. I mean nothing that could make living on my low (approximately $250 USD per month) pension-like income impossible. So I would have a free life.

And the SUV could be in the middle of the forest/field.

What do you think about this? Do you have any personal experience with any of these? Do you have any suggestion, recommendation or advice?

Thank you.
