As a mother of a son who wanted to go independent in his business 15 yr ago I know how you need support emotionally. I like your idea as a matter of fact. I think you have a lot more money than you are letting on! (Yes, my son is successful too BTW and everyone else told him not to go independent except for me. I encouraged him and I couldn't be prouder of him!).
I did not spend 80K on my set up. I got a used 1 ton dodge ram and bought a new 5th wheel last yr. I think you know how to budget your money much better than some "old people". I say go for it. If you are happy where you are living you will do better in your studies. Keep us updated.
