Engine 12 is a Ferrara, and the new mechanic is from Hillsborough County, and he said he prefers E-One. I think it's going to be more of an experimental truck to see how it goes to determine which manufacturer they'll use for future apparatus.
Ferrara is not my cup of tea. I didn't think an FDs apparatus was determined by the mechanic, it's usually by what's best for the department. If the Pierce units have been working fine then stick with Pierce and retrain the mechanic.
