Insurance in Hawaii

[wackerb]

I have a 2006 E-350 Sportsmobile which is too big to be a personal auto and I can't find a company that sells RV insurance in Hawaii. Geico, Farmers, State Farm, etc. don't offer anything in this market. Does anyone know of a company that operates in Hawaii? Big Island preferred but not required. Please don't respond if you don't know of one in Hawaii. Mainland experience does not apply here.
