It's an on road thing. ThunderbirdJunkie considered soaking his belt in WD40 or whatever it is the on road guys do to flexibilize their belts when he built his truck...but...he decided nah. No tangible reward in this scenario.

ThunderbirdJunkie is thinking the same thing of the belt, although it may be OK as long as you're not running over/underdrive pullies or landing nose down and wide open (as ThunderbirdJunkie has a tendency to do)
