I had vehicle writeoffs in excess of 100k and the depreciation is causing me to owe, I now have 2 days to reply to an exam letter after no help from turbo tax audit defense and had to go on my own. The irs rules I beleive should be different for commercial vehciles since I used a freighliner chassis rv to pull a 38k pound trailer but they are not letting me claim full or even half depreciation like I did per the turbo tax filing algorithm
