Best possible pay for experienced hazmat tanker

Hey all, I’m at a place in my life where I need to chase the money and find the highest paying job.
I’ve been delivering crude and refined fuels in addition to bulk products (pneumatics) in doubles for almost 20 years, no accidents.
I’ve got a job I love right now delivering fuel locally and home every night, but due to the extreme seasonal nature of my area, it’s not paying the bills. I’m currently located in Montana, but I’m willing to go anywhere. I’ve worked in the oil field in the past, and been over the road regionally (local states only) So I know what it’s like to not be home and I’m willing to do that again for the right job. I’ve got some leads on oil field jobs, but I have very little info about OTR specialized liquids or fuel transport. I’d like to make at least 2500 a week to make it worthwhile. I’m hearing that’s a possibility with the right company and route. Also I’m wondering if people can make the kind of money I need in a metro market with terminal based fuel delivery. Any input is appreciated. Thank you so much!
