We own and insure a Fuso FM260-based expedition vehicle with State Farm. The rate is reasonable, and the only company offering a possibly better package I found was Progressive. But since we have all the rest of our insurance [two cars, motorcycle, home, horse trailer, and liability umbrella] with State Farm, we could not use Progressive for only the Fuso without invalidating the umbrella liability policy. So we went 100% with State Farm.
Progressive's rate was roughly the same cost for the Fuso, but they offered coverage while traveling in Mexico, while State Farm does not [tho both do to Canada].

PS - Our registration is also as a motorhome.
