Crazynuff,
forgot to mention that if you run local you cannot take the Per diem deduction at all unless the load takes you away overnight.
If you leave at 4 PM and do not return until 4AM it is also not considered due to it being within a 24 hour period.
You must be in the sleeper or motel for the time allowed inorder to receive the per diem allowance.
But if you expend any other type of truck expense, like supplies, windex, paper towels, etc, you might get away with it. But remember I did not tell you this.
