As a large ticket item, you can deduct the sales tax from the purchase of your travel trailer as part of the sales tax deduction
The sales tax from your travel trailer purchase is a deductible expense, but you must choose to deduct either your state income taxes from 2016 (any income tax amount paid from your 2015 state tax return and the state and local tax withheld in 2016) or the sales tax from the travel trailer plus a standard sales tax deduction allowed by the IRS.
The IRS has a sales tax deduction calculator that can be helpful in determining which deduction is the most beneficial.
