Drag coefficient or not, any increase in airflow efficiency with my TC is always welcome, but then, I don't have the high frontal area that most of you do because I have a pop up so the roof is lower and the presented frontal area is less as well.... by about 18" actually.
I didn't excell at physics in high school.
One nice thing about my TC is, there is a number of convenient attachment points on the underside of the cabin over that are already there.
What's nice about the site I mentioned in the previous post is you simply input frontal area, weight, speed, drag coefficient (approx. .70 little more or less if you think your TC setup is a more of less aerodynamic than my TC setup). Out spits the hp numbers. No high school physics required.
Take a look at my air deflector in my profile page, I don't know how to post a picture since photobucket got greedy. I even turned my dually jacks into mounting brackets for side air deflectors. The picture shows those deflectors in painted white plywood and were temporary, they are now aluminum. Personally I think the best place for a deflector is just ahead or behind were the cab lights typically are, with the same curvature as the windshield, then angling back towards the camper jacks. I have 1.5" between cab and camper overhang, been that way for 60000 miles and 8 years with 0 contacts in that time but I don't go off road. It's been my experience that the Dodge frame has a little less flex than the Ford frame, this my be a factor in deflector placement.
O Edit: I looked at your profile page and see you have a crew cab with a fairly narrow short camper front overhang. JMO but what I can tell from the pictures I would start the deflector as far forward on the camper overhang as possible.
