As I previously posted, my experience suggests the 8" makes no negative difference other than easier to clean the top of the truck and the cab wall of the TC.
The air dams can cause their own problems. Unfortunately they are never posted on the forum.

It has been my experience there is a huge difference with and without a air deflector (not speaking about sleepy's air foil/brake). On my 2nd generation Dodge/Bigfoot camper combination I had a 5 in. gap between overhang and roof of truck. The wind noise was deafening, and terrible barrel noise effect coming from the 2nd gen Dodge roof as well. I unfortunately didn't take before and after decibel readings but it went from having to yell at my passenger and typically getting what or huh, it was annoying and stressful driving, with the addition of the air deflector this all changed to a normal volume voice being heard and being able to listen to radio.
All I did was add a 3.5 in. air deflector to the underside of the camper overhang. Now there is no difference in wind noise between camper on or off.
A minor side benefit is fewer bugs hitting the camper wall just behind the truck cab, the windshield of truck has also reduced bug hits by 70%.
Most truck/camper combination's are unique and will have vastly different results, fortunately my results were positive.
