We have used Lewis and Lewis for more than 10 years. I have found then very helpful and easy to reach by phone if you have questions. The nice thing is once you are a client you can renew your policy over the phone in minutes and they will e-mail or fax your new polity to you.
IMPORTANT: When you insure the motorhome there is an option for a trailer. Here you list your toad but under value of the toad enter zero otherwise you'll be paying twice. Then you take out the policy for the toad separately listing its current value.
