You can claim interest on camper payments on your taxes if three things are true: the camper has built-in sleeping, cooking, and toilet facilities; the loan is secured by the camper itself; and you itemize deductions on Schedule A. When those conditions line up, the IRS treats your camper as a second home and the interest becomes deductible home mortgage interest rather than nondeductible personal interest.1Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction Most factory-built motorhomes and full-size travel trailers clear the physical test easily. The loan paperwork is where people quietly lose the deduction.
Does Your Camper Qualify as a Home
A qualified home, in the IRS’s words, is any house, condominium, mobile home, house trailer, boat, or similar property with sleeping, cooking, and toilet facilities.1Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction All three have to be present. Miss one and the interest is personal interest, which gets you nothing.
Class A, B, and C motorhomes and standard travel trailers usually come with all three from the factory. Smaller units are where trouble starts. A pop-up that relies on a portable camping stove and a bucket toilet does not qualify. The facilities have to be built into the unit. A microwave mounted to the counter counts as cooking facilities; a Coleman stove stashed in a cabinet does not. A permanently installed cassette or standard RV toilet works; a removable portable toilet is a hard argument if the IRS ever pushes back.
How often you actually use the camper does not matter. Twice a year, full-time, anywhere in between. What matters is the physical setup during the tax year you are claiming.
Is the Loan Secured by the Camper
This is the single most common way people lose the deduction. The IRS requires the debt to be secured by the qualified home, meaning the loan agreement pledges the camper as collateral and gives the lender the right to repossess it if you default.2Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction – Section: Secured Debt
Standard dealership financing and RV loans from banks usually do secure the loan against the camper. Other funding sources do not. An unsecured personal loan is out. A credit card is out. A home equity line of credit on your house is secured by the house, not the camper, so the HELOC interest is only deductible as mortgage interest on the property that secures it, and only if the proceeds were used to buy, build, or substantially improve that property.1Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction Using HELOC money to buy a separate asset like a camper means that portion of the interest is not deductible.
Pull your loan documents before you file. If the camper is not listed as collateral, the interest is personal interest no matter how fully equipped the camper is inside.3Legal Information Institute. 26 USC 163(h)(2) – Personal Interest Definition
The Debt Cap and the One Second Home Rule
Even with a qualifying camper and a proper secured loan, there is a ceiling. Interest is deductible on up to $750,000 of total acquisition debt across your main home and one second home combined. Married filing separately, the cap is $375,000.1Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction The One Big Beautiful Bill Act made this limit permanent starting in 2026.
You only get one second home. If you own a primary residence, a vacation condo, and a camper, you have to choose which of the two non-primary properties counts as your second home for the year. You cannot deduct mortgage interest on all three. If the camper is your only property besides your main home, this is a nonissue.
The $750,000 is the combined principal. Owe $600,000 on your house and $120,000 on the RV, and you are at $720,000, fully inside the cap. Go over $750,000 and only the interest attributable to the first $750,000 of debt is deductible.
You Have to Itemize for This to Matter
The camper interest deduction lives on Schedule A. If you take the standard deduction, you cannot claim it. For 2026, the standard deduction is $32,200 for married couples filing jointly and $16,100 for single filers.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
Those are high floors. To get any real benefit from camper interest, your total itemized deductions, which includes state and local taxes, charitable contributions, medical expenses over the threshold, and mortgage interest, must beat your standard deduction. Paying $4,000 a year in camper interest with $14,000 of total itemized deductions and filing single means the $16,100 standard deduction wins. The camper deduction technically exists but produces no tax savings.
The people who actually benefit are those who already itemize for another reason: a large mortgage on the primary residence, heavy charitable giving, or high state income taxes. In that case the camper interest simply adds to a pile that was already crossing the threshold.
How to Report It
If your lender collected $600 or more in interest during the year, they must send you Form 1098, the Mortgage Interest Statement.5Internal Revenue Service. About Form 1098, Mortgage Interest Statement The interest amount from that form goes on Line 8a of Schedule A.6Internal Revenue Service. Instructions for Schedule A (Form 1040)
No 1098, either because the interest was under $600 or because the lender is not in the lending business? Report the interest on Line 8b of Schedule A. You will need the lender’s name, address, and taxpayer identification number on the dotted lines next to that entry.7Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction – Section: How To Report
Keep the original loan agreement showing the camper as collateral, along with something documenting the camper’s facilities. Nothing goes with your return, but if the IRS asks later, the burden is on you to prove the camper qualifies and the loan is secured.
If You Rent the Camper Out
Peer-to-peer RV rental changes the picture once you cross a threshold. Rent the camper for fewer than 15 days during the year and the IRS ignores the rental entirely: no rental income to report, no rental expenses to deduct, and your mortgage interest deduction stays intact.8Internal Revenue Service. Topic No. 415, Renting Residential and Vacation Property
At 15 rental days or more, you split expenses, including mortgage interest, between rental and personal use based on days used for each purpose.9Internal Revenue Service. Publication 527 (2025), Residential Rental Property The rental portion moves to Schedule E as a rental expense; the personal portion stays on Schedule A. To keep the camper classified as a residence at all, your personal use has to exceed the greater of 14 days or 10% of the days it was rented.8Internal Revenue Service. Topic No. 415, Renting Residential and Vacation Property
Drop below that personal use threshold and the camper stops being a residence for tax purposes. The Schedule A mortgage interest deduction goes away, though interest could still come through as a rental expense subject to passive activity rules. For most owners who rent occasionally and use the camper themselves through the season, the personal use test is easy to meet. If you are renting heavily through a platform, track your days.
