The average cost of RV insurance is $1,000 to $1,300 for class A RVs or $800 to $1,000 a year for class C RVs, as of 2015. Owners of class B RVs, which are the smallest RVs, usually cover them under traditional auto insurance policies.
Class A RVs, the largest recreational vehicles, are often the priciest to insure. The final cost of insurance is dependent on the make and model, year, size, and overall value of the vehicle. The location of the insured can also make a big difference in how much insurance costs. Class B RVs are conversion vans or camper vans, which makes them insurable under regular auto insurance policies.
