I purchased a rv using a loan through my bank. i sold the rv 2 years later for more than what i paid. i paid the loan off and pocketed the rest. do i need to claim that?

Yes, you will need to report this gain as the sale of a capital asset. (Just make sure that you actually have a gain before entering this transaction)

Your gain will be the net sales price less basis. Your gross sales amount can be lowered by any selling expenses. Your basis can include any improvement you made to your RV. Since you held the asset for more than one year, this will be considered a long-term capital gain.
