Credit unions are the strongest opening bid on RV money, often 0.5 to 2 points under banks, and a federally insured one is easy to verify through
NCUA. Marine and RV specialty lenders write these loans all day and sometimes beat everyone within a particular price band or unit type. Dealership financing is the convenient option, and the dealer can pad a partner lender's rate and keep the difference, so treat their quote as a bid to beat rather than a verdict. Collect at least three offers inside a two-week window, which the credit bureaus score as a single inquiry, and rank them by APR so fees are part of the comparison.
On a used rig, spend $300 to $600 on an independent inspection before signing anything. Water intrusion and tired appliances hide well during a walkthrough and cost multiples of the inspection fee to fix.
