Is interest on a RV loan (2nd home, yes sleeping, toilet and kitchen) deductible if it is not secured? When I toggle no, then it is not deductible; why?

[rjs]

No, it's not deductible. The reason it's not deductible is that the tax law says that home mortgage interest is only deductible if the loan is secured by the home.
