The air dam question came up in about 2009. I walked around the parking lot with a steel tape measure and checked air dam lip height. New trucks and old. They were pretty much all with 10" ground clearance.
Still my understanding that "no lower than lowest component on undercarriage" is general rule of thumb.
Making a slightly deeper front dam, but adding side skirts down the body, is my interest in the material.
