I saw a previous thread where people were discussing insurance and where to find it for your vintage camper.
My husband and I are both teachers and, as such, get a discount through Horrace Mann for our insurance. We have been very happy with them for car and house.
But I also want to let everyone know that they went out of their way to work out a way to insure my husband’s vintage ‘67 Mustang and my (not quite as vintage) ‘88
Scamp. So they may be a good company to check out if your current one is having trouble on the vintage front
