Who insures permanent campers?
I'm looking to buy a camper that will be in a permanent location, but want to make sure I'll be able to insure it.
Some of the more popular carriers on the market for RV insurance would be Foremost and Progressive. They tend to be the easiest to deal with, though almost all major insurance carriers should be able to offer a quote. The only exception would be if by "add-ons" you mean a permanent fixture on a campground. Some carriers may be less inclined to offers such coverage.
