Just got insurance in NC from Farm Bureau. No one at Allstate, Nationwide, National General, or anywhere else we called would do it. Farm Bureau spoke straight to the underwriters and was very transparent about it being a school bus conversion. They had to get it "seated" which apparently helps get insurance in high risk situations. It's insured as an RV, and our title says "House Car." $222 a year for 50/100/50 liability.
