We bought a motor home in 2016. Where and how can I deduct this as a 2nd home.

Yes. You can claim various deductions related to a motor house as a second home as long as your RV has sleeping, cooking and toilet facilities.

You can claim some of your RV expenses if you itemize. 

You will be able to claim any interest on a loan payment as the interest on a second home and the personal property taxes paid on your RV as property taxes on a second home. Please note that you will only get the benefit of these deduction if you itemize on your return and if all your itemized deductions are more than your standard deduction.

You can put this interest expense under your home section because the IRS considers this a second home for tax purposes.
