Hhhmmm. Maybe I will be the guy so we can see the outcome!!!
Thanks for the feed back. All good points. I would still do a small wind fairing. I have a sunroof, and don't have any intention at this time of adding the insert, so carrying items at the very front isnt a issue for me. I thought it was pretty even in slope from front too rear?
Bare in mind we are debating a 2" (?) difference in height and I still intend on using a faring, so the small differences in aerodynamics vs various load shapes and sizes along the length of rack I would call a wash without extensive knowledge and testing in a controlled environment.
So to keep it short and simple, piling crap on the roof will decrease aerodynamics regardless of configuration.
My thoughts were my unloaded daily driver (80% of miles) would have slightly less wind resistance, and what little difference in said height wouldn't be a big deal to me (if measurable at all) when loaded for camping.
Worst case as far as I can tell would be the want for lights in the future, at which point other mounting arrangements could be made. Some of the fairings I've seen haven't appealed to me, but at this point I've seen more pics without then with.
I do like the clear though RICKASHAY!! Didn't think I would. Also have to admit some LED bars integrated into a fairing with a simple cover too expose would be damn trick.
It has become obvious too me at this point that I need to cozy up in my chair with a beer and all the photos of the rack I can find and gaze at my Truck, and 'analyze' this further;-)
Cheers!!!
