Purchasing Camper Trailer as a Business Expense

[Seth Kellow]

Hello,

My Wife and I own several long-term rentals in the southeast. We now live in Arizona and I frequently fly back to the southeast to repair or inspect the properties and already deduct the travel, lodging, and half of the meal expenses from my taxes. 

If I were to purchase an Airstream to use as lodging while I travel across the US to my rental properties, make repairs, and perform lease turnovers, would I be able to not only deduct fuel and campground costs but also depreciate the purchase price across 5 years? 

Assuming I also use the Airstream for lodging while traveling for personal reasons, would I just take a pro-rated amount of depreciation for the amount of use that is business vs. personal? And how does the time the Airstream is just sitting in my driveway at my primary residence count?

I'll be talking to my CPA about this later this month but wanted to see if anyone else has done this sort of thing.

Thanks!
