I know there is supposed to be some logic behind the fire apparatus numbers in Camden, Burlington, Glouceseter counties as well as anyone else who uses the 3 or 4 digit system. I do know that for each county all apparatus ending in a number 1 is an engine, a number ending in 2 or 3 is a squad or an engine. I am really confused about the apparatus that ends in numbers 4 thru 8. E.g. Quint 4314 is in Medford Farms, burlington Co. In Evesham the ladder is 2235. It seems that each twp does it different, and this goes for twps in each county. How many counties in NJ actually use this numbering system?
