Asking parents to purchase a tiny home or RV in order move out, has anyone tried something like this?

I haven't as I feel they would be offended. But housing/rent prices are unreasonable, I'm single, and I'm in between a state where I can reasonably use SSI and being able to afford my own place. I pay for all my bills, including food and cell bills, and can also pay electricity/internet. I can probably make it work, especially with their initial support. It would not be a free ticket or a life of luxury, it'd probably be in a town they look down on and in a very low demand abode. My 12+ year work history shows I am not particularly capable of making enough to house myself, and section 8 is more or less decimated in my state. There's a chance it may go away altogether in the next 4 years. Which leaves my parents, who routinely spend enormous amounts of money (tens of thousands) on random things I don't even know about. My mom occasionally send me links of places that she should know I don't have the income for. Is it too much to ask that one of those purchases be a 10k RV on 10k land?
