To add to what Rin has said and links given, when you go to mount your Shadow Awn, consider height seriously. It's been mentioned in this thread in several places, in case you missed it (loooong thread...lol), but you don't want to have to duck or slouch when you're under it. Also, if you can't reach it when you go to deploy it, you'll need to remember to bring a stool or other lift to assist in both deploying and putting it away. There's a sweet spot for mounting height and it varies with owner, his family, & friends heights. Consider these factors when purchasing the rack, rails, tray or other brackets to mount your awn to your rig. Looks like you have a full size pickup that your truck cap is on, so mounting it too low should not be an issue.
