I have both a 7’6”x 8’ eBay awning and 4’5”x6’ Yakima slim shady. In my opinion, a 6’ is perfect for the length of the roof with an 8’ pullout. The quality of both awnings seem to be very similar, even the quality of canvas(not sure if that’s the right material, but feels and looks the same). Both have “leather” covers to zip up the awning with straps, same construction, and same locking tent poles. Only downside I can think of with the eBay awning is the mounts they give you which are L brackets. If I were to do it again, I’d go with the eBay awning in 6’, then buy the Yakima awning mounts. The Yakima mounts perfectly to the oem crossbars and came with locks.
Also, Amazon sells security nuts that screw on to the bolts that attaches the awning to the rack mounts.
Yak roof to awning mount
puts you around 250$ vs buying the Yakima 6.5’ at 329$. I have not checked ARB, iron man, etc for awning prices, so maybe you can also find something better made in USA!
