Using the DTS for business 100% of the time. You get stingy depreciation that could take 15 or so years.
But if the TRUNK is 6 feet long, you could get the 100% depreciation of pre-tax income, as if it were a 6,000 pound Esplanade.

So, can you tell me (measure if you must) have long is the TRUNK? Is TRUNK 6 feet long from the wall to the very deepest part?
