It's called CW insurance or inc or something. They are brokers basically. It's not them insuring. You will have to call and get the quote. They have different companies to go through.
When we got our TT three years ago, we called them and the lady called back with a quote through allied. We found it fair and went with it. We renewed this year. A month ago, we were trading in the TT for a motorhome. We received the motorhome before they transported the TT from the beach (4 hrs away) so we kept insurance on it to make sure it was ok. When I called to get the insurance for the motorhome, we couldn't have them both on the same policy for some reason. Believe it is a nc thing. So they (allied) gave me the number back to the CW insurance people. Te lady quoted me through GMAC (even though I had allied). Not sure why, but it may be protocol and they get bigger pay out from them or something. When the quote was twice as high as we were told It would be around, I said no and she got a quote through allied which was half the price for the same insurance.
But all in all it's CW insurance (brokerage) and they can get quotes through several companies. Just ask.
