I am the president of a large car club here in Montana and after years of being insured by Philadelphia Ins, they notified us that we will not be renewed at the end of our policy
They sited 'getting out of automotive events and car clubs' as a reason. I use Travelers here in Mt and they insure almost anything I throw at them including my truck/trailer .They are the least expensive, at least in this part of the world. I think a lot of companies are pulling back on stuff
good luck !
