I just ordered a Grandby shell and currently own the foxwing on my current setup with 3 additional tapered panels to be able to create sidewall coverage and more complete sun/wind/rain protection. I'm currently running a 2012 dodge longbed with cab height capper. Foxwing is mounted on yakima rack. I absolutely love it. It handles incredibly well in high winds (no problem with 35-45 mph with gusts 60+). Wind noise is minimal as well because of how secure the tiedown systems are. Each pole has a tie down anchor, and each section of the wing has an additional tie down point in the center that acts as a great way to funnel and shed rain water as well. The only downside is the necessity of 2 people to set it up in high wind situations. On a calm day, solo is fine, but you need the extra set of hands to hold the wing as you stake down each pole and wing panel as you go when it's windy. There are a few good youtube videos illustrating the how-to's. I'll let you know how it works once mounted on the fwc as far as rear door clearance when sidemounted, but its durability and ease of use is superb.
