Yes, the interest you pay on an RV loan should be tax-deductible. You should receive a statement at the end of the year from your lender showing you how much interest you paid during that year. To qualify for this tax deduction, your RV needs to have a sleeping area, cooking and toilet facilities, and the RV needs to be the security for the loan you used to purchase it. Not only is the interest from your RV loan tax-deductible, but so is the sales tax you paid at the time of purchase. If your RV is also your home, you can qualify for all sorts of homeowner tax deductions as well. If you work from your RV or use it as a rental, you can qualify for business tax deductions as well. Always consult with your tax consultant or CPA to make sure you are receiving all the tax benefits you are eligible for.
