If I was buying,Leasing a truck. I would take only a driver wage.
This is what I do, and the pay is the same every week, even if I don't work that week. My settlement direct deposits in a business account on Thursday night, and the salary portion comes out of that account into our personal account every Friday. I also have a maintenance account that gets $160/week thrown into it which never makes it into my business account (managed by Schneider).
Buying or Leasing, you MUST change your mentality from being a company driver immediately. Not doing so is why 99% of people fail.
For instance, I had a huge January, and a mediocre February (murphy's law attacked me for about 2 weeks straight).
And I highly recommend doing your books every month. It's nice to analyze profit/loss statements, fuel costs per mile, and other expenses to see where you can improve.
