Is it worth it to lease a tractor trailer and make money at it?

If you're going to be doing your lease through a company which pays 83 cents (or somewhere in that vicinity) per mile, don't expect to make much as far as money goes. If you can do your lease through a company which will let you select which loads you choose and avoid cheap freight, and which pays percentage (at least 75% and you should never accept less than 100% of the fuel surchage), then it can be.
