So no need for anything other than regular coverage etc?
If "regular coverage" means liability, collision, and comprehensive, the answer is Yes.
Pay attention to the "Personal Property" coverage in your policies, though. "Personal Property" is anything in or on the RV that didn't come installed on it, e.g. your clothing, computers, lawn chairs, and maybe even accessories like awnings and such. There is usually some Personal Property coverage in the comprehensive coverage, and you may have more if you have a homeowner or apartment renter policy for your home, but it may not be enough to cover all the stuff you have in the RV. A trailer hitch or toad tow bar alone may be several hundred dollars, so a mere $2000 of PP coverage doesn't go far.
