RV loan is tax deductible as second home. It doesn't have to be financed with home equity line of credit. The debt does need to be secured by the RV.

IRS standard from Publication 936:
http://www.irs.gov/publications/p936/ar02.html"Qualified Home
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.
The interest you pay on a mortgage on a home other than your main or second home may be deductible if the proceeds of the loan were used for business, investment, or other deductible purposes. Otherwise, it is considered personal interest and is not deductible."
