[quote author=Ned]Since you have both homeowners and RV coverage, a separate liability policy covering both makes sense.[/quote]
Makes no sense to me. Our liability (aka umbrella) policy doesn't "cover both". It's a liability policy unrelated to other policies we have. OTOH, like Bernie, a requirement of the umbrella policy is that we carry a defined minimum liability coverage on the policies for our boats, cars, and RV. The umbrella policy kicks in when any other coverage (or non coverage) stops paying. It's a personal liability policy, not specifically for a boat, car or RV.
