Sorry about that, we actually had a few changes and the new awnings are 79" versus the older 70" models. I just had our web guy update that on the site.
The awning will sit flush with the top of the pioneer roof rack system from Rhino Rack. Feel free to p'm me and I will get you set up with the hardware for the rack to awning connection.
Thanks for the update. I'll be in touch this week to place an order.
