Is this a financially stable way to live?

So I (24M) live at home with my parents who are soon going to kick me out. I have about £30K saved and I work full time as a retail assistant bringing in £1,600 a month after taxes. I’ve always wanted to live in a caravan since I was a kid and feel like I’m probably going to do that in the near future anyways as I’ll have nowhere to live. I’ve seen some really nice and spacious caravans for sale within my budget and honestly, some of these look better than flats. So my question is, would I save a lot of money by living in a caravan and working full time? Would seriously appreciate some detailed answers!
