Does home owners insurance cover RV damage due to weather?

No it will not. You have to purchase a policy specifically for the RV. You homeowners policy excludes self propelled vehicles of any kind except for lawnmower used for the upkeep of that property exclusively and Golf carts. Any others like cars, trucks, RVs, ATVs, boats over a certain size limit, and anything else will be excluded from coverage on the homeowners policy.
