Ray,
Explorer is the insurance agent, and National is the insurance company. When I called Explorer they gave me the 800 number for National and it was as easy as that initially. I had my claim number and knew the bus was going to Jacksonville. They had no issue with the SC state police calling a suitable tow truck, and from that point on I was in charge. I sent the first tow truck away because the driver did not impress me as capable and the truck seemed less than capable.
When the bus was sitting on site at Prevost I talked to the adjuster assigned to the coach. He listened to what happened, arranged to look at the coach and along with the Prevost manager authorized the repairs to be made to the standards we three parties agreed were necessary.
One of the keys to my success in getting the proper repairs was the fact the adjuster who was a direct employee of National was he was completely familiar with buses.
