Joel, here's a radical idea for you based on my very selfish need to install a "low-profile" rooftop tent. Well, relatively low-profile when compared with how high the install would be when installed directly to the factory rack (add 12-14" to the existing rack height - not ideal)!
Can you give some thought to the possibility of machining some bolt-down Yakima-style towers to completely replace the factory rack? Ideally these towers provide a *level* platform (i.e., each pair of towers would likely be different heights for a *level* load platform), to install Yakima load bars so a rooftop tent (or any number of other available Yakima/Thule a
ccouterments) could be installed with roughly 1-3" of space between the tent floor and FJs roof.
Is this something anyone else besides me might be interested in? Thoughts?
