I am trying to find a good company to provide us with cargo insurance. My husband has a 4 car hauler and currently works for a transport company. We are wanting to go on our own, but need cargo insurance.
I'm not sure that I can recommend a specific company, but for "ease" of getting your insurance, you can't beat CargoCover.com. You can do everything online, and can get insurance specific to your cargo for each run. You can review, change, reprint or cancel cargo insurance certificates, all online. You can even start the claims process online.
Just keep in mind that there are many companies that issue cargo insurance, and you should always shop around! You may find that you can get the same ease of use and a lower price with another carrier.
