Heavy duty truck maintenance issues to chew on

• Weight makes heat and heat makes wear -the heavier you haul the more maintenance required - shorter service intervals. 
• Dirt hides the sources of maintenance cost leaks - dirt traps heat, hides loose fasteners and prevents putting an "eye" on potential trouble spots.  The moral - keep what's inside the frame rails clean with high pressure spray.
• Trucking manufactures are notorious for having customers testing new products at the customers cost.  -don't be the first to try a new major component or truck model unless you are prepared for uncompensated down time. Often, (too often!) new truck equipment products don't work out well, particularly early on.
• Remember, low price is not as important as low risk.  Poorly engineered new trucks and or poorly maintained used trucks are lower priced for a reason.   The market place figures this out and assigns appropriate relative values at the used auction block.
