Awning Walls double as Shower Shelter
Looking at options for shower shelters, a la Tacodoc's thread, and also wanting some panels to finish off the awning to provide some more shade and wind protection, I decided to combine both. I contacted the folks at SLO Sail and Canvas who made my rain fly. (They now produce them for sale by AT, I believe.) I took copious measurements and sent in the design via email.
It's a single panel that runs from one Flippac latch to the other. The top of the panel has velcro straps to attach it to the awning and the bottom has grommets to stake it down. The "ends" have nylon loops to attach it to any point on the truck with rope, straps, or bungees if necessary. It has a zipper in the middle for access. If I only attach it on one side, I can wrap the wall around the awning pole and back on itself keeping one side open like in the third pic.
Unfortunately, a beautiful calm morning turned windy the instant I started attaching it to the awning so it flew around a bit in the pics and there was no way to stake it down to the driveway. I strapped it to a wheel on either side just to get the pics. I think if I were in dirt, I could have battened it down nicely with as many grommets as there are. SLO Sail and Canvas attached wide nylon webbing around the entire edge so I think the grommets and straps will put very little stress on the fabric.
I got it in the same green fabric as my rain fly to match and to provide some protection in the rain. There is a 1-2" gap between the awning support and the awning itself so it's hardly water tight but it will provide some protection from the rain regardless, especially if the rain it coming in at all sideways. I'm very happy with the results as it fits perfectly, which is pretty cool since they've never seen the truck.
