If you look up on this thread you'll see the steel brackets I attached to my Alu-Cab RTT to lift the awning above the hatch. I'm sure you could very easily do the same with the Gobi. i just looked up the Gobi awning brackets for the alu-cab and you could easily a piece of flat stock to them to raise the awning, much as I did with the alu-cab RTT.

Although the Peregrine 180 looks interesting and especially at half the price of the alu-cab -- I must tell you that the alu-cab awning is rather remarkable in the ease of its deployment and stand alone wind resistance. I have used it without any support legs in the middle of Joshua Tree spring winds where I was having a difficulty staying upright, but the awning held strong no problem.

Somebody mentioned the bundutec awning. I don't have any personal experience with that, but it looks cool. It's bigger and covers more of the rig, which seems to be most ideal if you're attaching to a stand alone trailer -- but a little irrelevant if going on top of your 4-runner as the extra panel only covers the hood of the ride. However, it too will likely run you closer to a couple grand when tax and shipping are included.

Hope this helps.
