Really depends on whether you plan on full timing or just part time. Get quotes from all major insurers if you are part timing. If you are going full time, only certain companies write policies that cover the extra liability needed for that. Rates will vary widely depending on class, age, your driving and credit history, and by company. I have my full time toy hauler insurance through a subsidiary of Nationwide that Good Sam's was the agent on. Very good price and offered the coverage I needed. Good luck.
