Long been a dream of mine to become a cattle hauler

Edit- title was cut short, should say on top of student loans and essentials, what should I, 20M, do?
I'm currently in college for construction management, and will graduate in a couple years. Right now, I am on a leave of absence, though, and working construction. I currently have $7,000 in the bank, plan to continue working a $12.5/hr construction job (after taxes, healthcare, social security, etc.) full time until around January, when I will return to school full time. I then have three and a half semesters to complete afterwards, since I've taken a couple summer classes this summer and took some last semester and this upcoming fall semester. By the time I return to school for the spring semester, I should have a total of $16,000-17,000 in the bank. I will then work the summer of 2023, which will likely bring me to around $24,000 in the bank. Then, if I work again in the summer of 2024, I will be up to around $32,000. If I take the next semester, the fall, to finish college, and then work full time right after college, while still living with my parents, I can get to around $57,000 for 2025 and then one more year living with my parents I can get to around $82,000, which is finally enough to afford a dually 1.5 ton truck and a livestock trailer to start my dream of hauling livestock. I know a semi would be a better option, but I can’t imagine being able to afford it just yet. I’m thinking about starting smaller scale, pulling a 30 ft trailer, which will also likely get me a better chance of getting more experience with cattle.

However, that would then leave me with nothing in the bank, and I can't live with my parents forever. Perhaps I could for a time turn the trailer into a makeshift home, but even then I still have to worry about student loans, food, clothing, etc. In addition, I also hope to someday afford a Peterbilt 389 sleeper and a larger livestock trailer. Of course, I'm not taking into consideration that I may at some point be given a raise/promotion at my current job, especially when I graduate with a degree in construction management and get my CDL, but even then I'm faced with the challenge of having to somehow come up with between $200,000 and $300,000, on top of student loans, fuel costs, and costs for essentials. I'd be perfectly happy living in the Peterbilt for the rest of my life, right now, although I may not be in the future, so perhaps I should also add to this list of costs that I need to at some point be able to afford a home.

What should I do? Should I skip the 1.5 ton dually? Should I stick with the construction job a little longer? Any advice?
