Guys, for it to be a quint, it must have 5 components. Thus naming it a "Quint". Those 5 are as follows: Pump, Water Tank, Hose, Ground Ladders, and an aerial ladder (It can be a Tower, Mid Mount, Tiller, etc.). As long as it has those 5, its a Quint. With this truck having a 500 gallon water tank, unlikely. The biggest that I've seen a truck like this have is 300 gallons. But its you're truck, and you can do with it what you want.
No. Quints are Ladder trucks with Pumps. For instince Pleasant Hills truck, its a Tower, but has no pump, therefore it makes it a Tower-Ladder. But if it has a pump, like Castle Shannons, it can be considered a Quint or a Towe-Ladder. So really, he can call it what he wants. -Lee
