Wow. That's strange. We haven't heard of this issue, but clearly as the name of the product implies, it should work! Looks like there may have been a change to the Eezi-Awn brackets in the time since our engineers designed these mounts. They have been made aware of the problem and are looking in to it. In the meantime, we will gladly take a return on the brackets for a full refund, or we can put you on a list to swap the Front Runner Brackets out if / when we end up making a revised version of our mount.
Please feel free to contact us through any of our support channels - phone, email, web contact form, live chat - so we can help you out on a case by case, customer by customer, basis. Thanks!
And if you haven't already, watch this video we made about our Awning Brackets!
