As far as I know, National General has only been selling RV insurance under the name of National General since 2012/2013 as it was formerly the old GMAC insurance. We had GMAC when it changed its name to National General. I was not happy with their customer service nor their premium structure and they also sharply raised their rates for us shortly after the name change.
Companies also needed to offer full-timer coverage for those who live year-round in their RV; full replacement coverage in the event the RV is totaled or stolen; personal belonging coverage for the property inside the RV, including electronics, appliances, and jewelry; vacation liability coverage for injuries that occur at the vacation site where the RV is parked; and permanently attached items coverage for items like satellite dishes, wheelchair lifts, or retractable canopies. Finally, companies also were required to cover most, if not all types of recreational vehicles.
