We bought a 2000 International 4700/DT466E crew cab truck to haul our gooseneck racing trailer. Its in-between your 1 ton dually and semi-truck cab. Its considered a commercial truck. I called my insurance (progressive) and they won't touch it as a private vehicle. I would have to get some expensive commercial insurance?????????????? I have yet to talk to someone who is really helpful. How are you insuring your rig/hauler?
