I think the Linde H45D, 352 series diesel truck is the longest lasting, bullet proof truck with the lowest maintenance. We have customers that have put up to 40,000 hours on these trucks with rebuilding the engine or touching the hydrostatic drive. The radiators were solid aluminum and the steer axles were massive. You can drive one of these trucks that may have 20,000 hours on it and you would swear it only had 2000 hours. The only issue was that they ran so cool in colder climates the cab heater didn't put out enough heat.
Super quiet, super smooth and ultra dependable!
