Knapheide's SubTropolis Upfit Facility

Truck and van upfitter Knapheide installs equipment in Transit vans at its underground SubTropolis upfitting facility that's part of an active limestone mine outside of Kansas City near Ford's Kansas City Assembly Plant. The ambient temperature and low humidity of 65 to 70 degrees Fahrenheit eliminates the need for heating and cooling. Photos by Paul Clinton and courtesy of Ford.
