Because everyone keeps asking about insurance or doesn't realize how expensive it is...

Here's a quote from progressive (one of the few insurance carriers that may insure you). This is a typical hotshot setup. 10 year old 3500. Gooseneck flatbed trailer. 1 mill liability (required by most brokers) 250k cargo. Your exact pricing may change a bit, but this is a good number to use to get a rough idea. $8600 per year.
