My '85 Westy is insured as an RV with Progressive.  My agent tried several
companies before finding one that would go this route.  Not as cheap as
antique insurance, but I don't have any mileage restrictions.  It is still
about $450 per year, but that is about half what my '89 Jetta costs.   My
'65 Corvair is like $60 a year for antique coverage.  You can only have RV
or antique insurance if you also have a full coverage policy on another
vehicle--in other words you can't have an antique or RV as your daily
driver.
