RV loans can extend up to 20 years, making monthly payments seem manageable, but the true cost goes beyond simple interest calculations. Longer financing terms keep you underwater on the loan longer, meaning you owe more than the RV is worth for most of the loan period. This becomes expensive if you need to sell, trade, or if the RV is totaled in an accident.
The depreciation curve works against extended financing in ways that aren’t immediately obvious. RVs typically lose 20-30% of their value in the first year, then continue depreciating steadily. Meanwhile, longer loans mean smaller principal payments early on, so your loan balance drops slowly. Many owners find themselves owing significantly more than their RV’s trade-in value even three or four years into the loan, limiting their options if circumstances change.
Insurance gap coverage becomes more critical with longer loans, but many policies have limitations. Standard gap coverage might not include additions like solar systems, upgraded appliances, or other modifications that add to your loan balance but don’t proportionally increase the RV’s value. If you’ve financed extras or rolled negative equity from a previous RV into the new loan, standard gap coverage may not bridge the entire difference.
A practical approach many experienced buyers use is financing for the longest term available to keep payments manageable, then making additional principal payments when possible. This provides payment flexibility during tight months while reducing the total interest paid and building equity faster. Even an extra $100 per month toward principal can save thousands in interest and years of payments on a typical RV loan.
