LBPtaco - your setup is an idea that has been rattling around in my head for sometime. How does it attach on the sides? I had toyed with the idea of Velcro or snaps on the outside of the canopy. Really inventive. Did you make a fly for the entrance, maybe screen material for bugs? Thumbs up!
For attachments there are grommets that I tie a line thru and run up to the wheel well and another up to the door jam, theres also 3 along the bottom that I havent figured out where to secure them. I thought about snaps to the shell and bed sides, but I didn't want to drill holes unless I really needed to. When the tent is properly secured it sucks up to the truck real nice. I did not go with a fly or screen for the entrance, the material is marine grade waterproof canvas so I'm not worried about leaks, and for the ventilation I can open up the sliding windows in the shell itself which have screens so the bugs cant come in. If you would like I can take more pics this weekend of attachment points and such.
