Whats the MOST miles a driver can do in a month as a single?

A lease operator MAY make 120 gross a yr, but what was net....most likely less than a company driver. Folks need to remember lease benifits the COMPANY NOT THE DRIVER. Otherwise they would not push it so hard.

there are really 3 ways to do it.
1. Lease & team with your wife/spouce so all the $$ goes into 1 bank.
2. Be a trainer...but some companies (swift for shure) takes away 5 cents/mi for you having in their trainee in your truck.
3. Buy a truck from a stealership, then contract to a company.

all have + and - but just know that 120K/yr means nothing, if your expences are 119,000 all you have is cash flow. (remember 5K for a set of tires, fuel ~ 400-600 every couple of days depending on the miles you run), and what happens when the truck goes in for service Still $500 for this weeks payment, & the truck just sat in the shop for 4 days cause the pink antifreese is eating up the water pump, & needs to be swapped out...covered under warranty, but your lost wages are not).

IMHO Drive hard when I am away from home so I can afford to take time off & have the money to do what I enjoy when I get home...I am also a Company driver. It seems to me a local driver running a specialized truck that not many folks have, but is in demand in your area is the profitable way to be an OO.
