How custom can things get with Dragonfly tarps? I'm hoping I can get some specific colors and a pattern that I'm looking for. A tarp is a ways off for me, but I like having a plan.The awnings are made out of a ripstop nylon that has a urethane coating to help with water repellency. I usually stand in my door and slide the tarp into the channel, and there is a stop at the end of the channel at the back of the fan to prevent the tarp from sliding out the other end. The aluminum channel is called Keder and is attached using 3M UHB tape. On my van, the prototype, I actually used screws to attach the aluminum channel and on dads we used the 3M.
