I happen to be selling mine actually. I'm planning on going back to a hard camper shell so I took off my topper (Bestop Supertop) the other day.
I'm selling the topper with a brand new, unused skin as well...so the thing is essentially brand new. The skin I currently have fastened to the skeleton has some cracking around one of the plastic anchors (but is still perfectly usable, I ran it for 4 months how it is), so I picked up another one. The only thing you would need is the adhesive velcro strip that sticks to the bulkhead to anchor the back wall. You'll see what I mean in the instructions. I can't imagine it'd cost more than a few bucks. They may even send it for free.
I love the versatility of it, but I'm just going a different route with my build.
PM me if interested. I'm located in TN, 37042 area code. I only had 1 picture small enough to attach. I'm on mobile out of town. Shoot me your email address and I can send you a handful though.
