If you're an owner-operator (OO) who drives for a living, the relative well-being of your rig is likely one of your top concerns and priorities. After all, having your semi truck sitting in the shop awaiting repair means it can't be on the road helping you earn money. However, in an uncertain political climate (one in which the EPA is seen as under attack), you may be reluctant to spend tens or even hundreds of thousands of dollars on a new truck if the environmental regulations that have contributed to its higher price are rolled back or rendered moot.
