Awning SunShade

we have the 4.5ft x 6ft Tuff Stuff awning with the shade wall . IMO the shade wall works good to block sun or rain & also works very well as a awning extension with 2 Green Elephant adjustable tent poles.
Looking at the ARB foxwing awning and wondering if it works and fits on a Front Runner full length roof rack. Any issues with fitting and deploying it? If you have one and can give me some pointers it would be appreciated.
