Boom Truck Crane will cost more....but should not cost a lot. Bucket truck will be very reasonable. I think I pay around 4500 a year to insure my entire fleet...and that consists of 5 trucks...one being a crane that was bought new a few years ago. You have to shop around with insurance companies....it pays. Took me several years before I found one that I was happy with...and that provided me reasonable coverage.
