Try GMAC. You can probably only get the bare minimums for your state. I don't remember what AL requires. I used to know when we lived in Chattanooga since we were so close to the state line. If you are already titled as a motorhome/RV then that is what you are insuring. Based on my dealings with the insurance companies, more than likely, they will never pay off on your bus, so I figure why pay them the higher premiums only to be told the bus is worthless. I'm still PO'ed at Nationwide and how they treated me when one of their customers hit my Caddy. They said my Caddy was worth $900 and they would buy it from me for that and total the car. I told them find me a Caddy, same year same shape (pre wreck) and we could swap Caddies. Got nowhere with that proposition. So I can image dealing with a insurance company over a home converted bus.
