railrocker,there are several insurance companies that specialize in insuring collector vehicles.I have my old trucks insured thru my regular company at an agreed value.Chances are that if you find a company that will insure your old truck at an agreed value they will also want the rest of your business,house,daily driver vehicles,etc.Check thru the Classic truck magazines ,there are several companies that advertise in there.My insurance co.Grange of Ohio lets me appraise my own vehicles,and they also want pix of them. I carry full coverage including collision,and liability in the summer months,then in the winter months I only carry comprehensive on them.Fire,theft,etc.
