Conestoga Custom Products Inc., or just Conestoga, was an American fire apparatus manufacturer located in Leola, PA (later Ephrata, PA). They operated from 1978 until approximately the mid-1980s.
Conestoga was founded by LTI's founder Mahlon Zimmerman in 1978, a few years after LTI was in 1974. Their facility was initially located a few miles away from Ephrata, in Leola, until they moved to LTI's newly-built factory in 1980. They mostly built pumpers & tankers for the first couple years, until they morphed into being an in-house builder for LTI's ladder trucks. They also ended up making a few trucks badged for Mack and FMC as well. It appears that the company was still building some trucks under the Conestoga name in the mid-1980s, but presumably stopped shortly afterwards.
