Roof Tent Fairing Thread

[theferg]

I've just picked up a roof top tent for the top of my 3rd Gen 4runner. I plan to mount it towards the rear (centered over the rear axle) on the factory roof rack rails and I'm trying to figure out what to do for a fairing to try and cut down the drag. I've found a couple threads here and there that reference fairings, but they seem to be geared more towards whether or not a fairing does anything. I'm looking more for ideas on where and how to mount the fairing in relation to the RTT in order to minimize the drag. The tent is about 47"x47"x12" when packed up.

So what are your ideas and thoughts on a fairing? Any idea where would be the best position to mount the fairing so as to best push the air over the tent at highway-ish speeds? Given that if the fairing is too far in front of the tent it might hurt more than help and if its too close to the tent it might not do much of anything.

Also, what's a good design? I figure that the smaller the slope, the better the airflow which would result in less drag... but not sure I want a 4 foot long 15-degree fairing sitting up there. At least I don't think I do...hmmmm...actually that might not be such a bad idea... I won't be running with the tent 365 days a year so putting up a 4 foot long fairing when I put up the tent prob won't be that much more work. (Sorry, kinda thinking out loud a bit now.)

So throw up your thoughts and ideas if ya feel so inclined.

I have an idea for one that i will be working on fairly soon. I am going to use aluminum for the structure and the skin. I plan to go out 24", flat on the bottom, and angle from front to the top height of tent. Also will be easily detachable so it does not interfere with the bows over the windows. I will mount it close to the tent. Well see, its got to be better than the aerodynamics of a box!

I know yah got a 4 runner but I used my roof rack basket like. made it flat and cut and bent the fron end .. this made the fairing rather easy and I get no wind drag at all....well I dont feel any but then again im driving a brick uh.....

I bought 4 load bars outback brand, with the idea to use 3 for the RTT and one bolt on top small faring with a solar panel on the slope part. I was thinking fiberglass resin impregnated thin carpet with some MDF structure
