How does voluntary repossession work on an RV in NC?

Instead of having it forcibly repossessed, you call your finance company and tell them you're voluntarily having it repossessed. They may send a tow service to collect it, or they may ask you to take it to the repossessor. It'll be repossessed, auctioned off, and the amount they get from the auction will be deducted from the amount you owe. The finance company may offer a settlement at that point for an amount less than what you owe on that vehicle - that's up to the finance company.
