One company you might want to check with is (Dang can not remember the name on my license) Primarica.. Warning, they are a bit like Amway in that they may want to recruit you as an agent.
but in most states they do not sell auto insurance.. BUT they used to have a tool (online) where you could enter your stats and they would shop several companies for you and give you comparative rates.
Also, if you belong to FMCA or Escapees or any other RV origination, they may hae a package deal for you too.
NOT: I am no longer affilated with Primarica, and even if I was, I would not benefit in any way from your contacting them.
