haha...3M tape. That's funny.
You know, I haven't ridden in or driven it since I installed them. Cross bars are separate either from the dealer (I think LR units are Thule), or from someone else. I'll probably go with the Rola units mentioned by a couple people elsewhere on this forum.
Do you need tools to install? A 13mm socket..that's it. I have the pano roof though keep in mind...the non-pano roofs have a similar install but need finishing parts that go over the roof gutters. You'll see that in the LR parts accessories list.
So basically you remove two plastic covers at the front sides of the roof towards the windshield, and two plastic covers at the rear sides of the roof above the rear side windows ahead of the rear hatch. Once removed you see threaded bolts that are built into the body of the truck.
In the roof rail kit are metal mounts that mount onto these bolts which are fastened down with the included 13mm nuts. Once the six mounts are in place (two at front, two at 3/4 rear, two at rear), then you take the rail itself and place onto these mounts which then fasten with 13mm bolts. Again, took me less than 30 minutes to complete.
