What if I want to add upgrades or accessories to my RV?

Do I need a certain credit score to finance an RV?

While credit history definitely factors into your financing options, don't get too hung up on having a certain score. Part of the reason we work with several different lenders is so that we have options that work with as many lifestyles and budgets as possible. Instead of wondering if you'll qualify, the best thing to do is start the process and our team will guide you through it.
