The pictures pretty much tell the tale. I wanted a leg on either side to support a long piece of PVC pipe going across the width of the tent with the iPad holder in the middle. I used 3/4" PVC pipe. This is a pup tent so I wanted it just high enough so that it was out of the way but also so that I could just raise my arms to reach the iPad controls and to adjust the tilt angle. I used PVC cement on only a few of the fittings; mainly just so I could see what piece went where when we arrived at the campsite.
