Possibly a dumb question...but in the pictures below, what is the horizontal bar thingie that's on the side of these two boxes towards the rear? I assume it's for mounting something, but I can't find any photos of trucks that show anything mounted to them.
Based on boating “sail track”
Great solution to attach cloth like material to the side of something. Creates an almost water tight joint. For those looking for a light weight option or if you rarely use an awning this provides great option but you do need poles or attachment points/ tree. The best part is you can decide what track length and what size “sail” length you want
This is the opposite spectrum of a motorized awning
