That is the same as owning a house, as long as you reside in it and use it for personal reasons.
This, from IRS Publication 936:
For you to take a home mortgage interest deduction, your debt must be secured by a qualified home. This means your main home or your second home. A home includes a house, condominium, cooperative, mobile home, house trailer, boat, or similar property that has sleeping, cooking, and toilet facilities.
