Roslesters55,
I have a 46 1/2 ton, 2-52 1/2 tons, and a 63 Falcon convert. All of them are fully covered by my regular insurance carrier, Allstate, with $0.00 deductible on Comp. and $100 deduct on collision.
They don't have a limitation on mileage like most of the Classic/Collector car insurance companies. Additionally, they didn't require an appraisal, and I can put any of them in a "storage" status, (and save some money) at anytime I'm not gonna drive them for awhile.
I've been told, and fortunately have not had to put it to the test, that should something significant happen, I just need to be prepared and able to submit proof of value when filing the claim.
Good luck.
