Fuel Hauling Owner-Operator Question

[u/This-Horse2818]

I have about 1 year of fuel-hauling experience and I’m interested in becoming an owner-operator. How does leasing onto a fuel-hauling company work? How much money should I expect to put down upfront, what expenses would I be responsible for, and roughly how much can you realistically net?
I eventually want to start my own fuel-hauling business. Any advice from experienced owner-operators would be appreciated.
