Old post. But I am hoping I can help others with the information that I found. It took me a while to figure it out. You can take depreciation, interest, property taxes, cleaning, and advertising fees. There is a vacation home rule. You need to know how many days you used your RV personally and based on the number of days, you can write off your rental RV ( partially or fully). If you used your RV personally for less than 14 days, then you can deduct the whole RV. If is used your RV personally for more than 14 days, then you will need to prorate your personal and business expenses.
