Exactly Bob. In reality any of us can write off the entire cost of our motorhome and all of our toys. And you won't have a problem at all unless the IRS catches you. :) If you don't get audited you're fine. If you do, you better get your checkbook out. I love how people make these claims of what they write-off and how since they haven't been caught it must be legal. Like put a sign for your business and then all the sudden the entire motorhome is a tax write-off? Not a chance. The cost of the sign you put on the motorhome is a deduction under advertising expenses on the schedule C. Try putting a motorhome under advertising expenses and see how fast the audit comes.
