Just a different look into things. Mits,cat, and yale used to all be built by raymond just with the ev-100 system, crown uses ev-100, mits and cat are jungheinrich now. Raymond uses its own system but it is expensive..how much difference is there really in the narrow aisle and sit down market? Crown is known for it's thicker frames as well as clark, the rest are basically the same. Even most ac units use the same zapi system...all bias aside is there a lot of variety in this market?
