Ian-Seconding the thanks Harbinger! The pictures confirm that it will work and that's everything I need to know.
Ray - I would suspect that it'll play really well in the back of the 3. Can you say more about what the additional runners would do for your installation. I have no doubt you've got a vision; I just don't see it yet? Wouldn't this hang off the 2nd row and 3rd row handles just fine (sans runners)?
I think it would hang off the handles great, as depicted in Harbinger's photos. For me-even though we're all short-I'd prefer to keep the headroom and thus really want to find a way to keep it in the rear cargo area vice the straddling the 2nd and 3rd row. Here's a few shots to illustrate what I'm thinking-and I'm not wedded to the idea yet but getting closer to pulling the trigger on BROG attic to try it out.
Dimensions for the attic are 36"x24" from what I'm tracking online, and based off Harbinger's shots-it clearly fills the side to side space well so my thought was how do I best utilize the 3rd row moonroof cavity and take advantage of the same ability to mount things up there that the mantec attic does (i.e. the handholds attach to roof with screws)? Here's the rearmost area that I'm talking about:
An unsteady, it's raining in the NOVA area, iphone shot showing approx 22" w/o bending too much of the 'runner' that I have in mind:
Back in the garage with a piece of flat alum stock showing my idea for a runner, I would likely go with thicker and wider stock than this so I could, conceivably, cut out the hatch light area so those were still useful. Likewise I am considering making the runner the full 24" length and just to some bends on them to follow the contour of the roof but am undecided if that would work as well as keeping it up close to the moonroof to mitigate how far down it hangs and just let it be a little less than the full 24" fore/aft measurements of the BROG attic. Clearly the metal and the bolt plates would get painted to match the headliner color and such. All stuff that could get sorted after getting the attic on hand though....
As if I needed more stuff to buy for my truck!
