All my parts finally arrived and I was able to find time to get it done. I bonded 8 anchors onto the ceiling of my topper using JB Weld plastic bonder.You did it yourself? I know that Leer offers a ceiling cargo net option from factory which uses the butt ends of the roof track bolts. I had considered getting that when I ordered my topper, but once I realized it wouldn't be that hard to add myself and that I could get a set of tracks, towers, and bars for cheaper than Leer was charging, I abandoned that option. I have plans to do a similar setup once all my mounting hardware shows up.
My plan is to "glue" some mounts to the ceiling (not use the track bolts which I don't have yet) and hang a net from them. I'll only put it on the left/drivers half of the roof so I can easily access it through my drivers side windoor on the topper. And I already have a cargo net the perfect size. We'll see how it works. I don't plan on putting heavy stuff up there, and the tension strength of the adhesive I chose should be high enough to support some maps, hats, and sweatshirt or two.
