As far as fuel is concerned, you have to keep in mind the mileage the gov't allows; last time I looked it was north of 50 cents/mile.
So after 10 miles, that 5 bucks. You may want to just keep track of the mileage on the truck. Maybe knock of 10% to be on the safe side and call the rest of it mileage. 10 k miles = over 5 k in writeoffs. However, if you use this method, you can't writeoff repairs, oil changes etc, because that 50 some cents a mile is taking that all into account. Including insurance on that vehicle, I believe.
VERY important point...you beat me to it, but I wanted to second that:
You
EITHER write off actual vehicle expenses (fuel
and depreciation included) OR standard mileage rate (48.5 cents), but NOT both. If you choose milage that is all you write off.
You cannot use the standard mileage rate if:
*You have used actual expense on the same vehicle in the past (I think since 1997...)
*You have 5 or more vehicles operating for the business at any one time
*Other stuff that wouldn't generally apply to us tree guys...
If you have a vehicle you don't put many miles on, you are likely further ahead writing off actual expense - more paperwork, but the depreciation on a low mileage vehicle is likely to outpace the 48.5 cents per mile. More expensive trucks or trucks with very low gas mileage are probably better off with actual expense too. Besides if you are depreciating it, you have to get a new (or another used one) one every 5 years to keep the write off coming :biggrinbounce2:
In all honesty, this isn't the best place to be getting tax advise...we in't joining you in court if things don't work out right
I don't have a CPA, but I spend a lot of time reading IRS pubs. It is a royal pain the first couple of years, but gets better once you have been through it a couple of times. I used to do it all by hand. Spent about $60 on HR Block brand "Tax Cut" software last year - well worth it.
There are a couple of pages here that will tell you more than you want about milage:

Here is everything (and much much more) that you would ever want to know about depreciation straight from the Man:
http://www.irs.gov/instructions/i4562/ix01.html
and the form to do so:

Many of the normal business write-offs/deductions are covered on
Schedule C
Schedule C instructions (see especially Part 2 starting on page 4).
