Question:
Your add for the Retrax Pro MX retractable tonneau cover for a 2021 GMC Sierra 1500 shows that the bed rails are the wide rails that cover the stake holes on the bed. Your add is the only one that I have seen that shows the optional wide rails for this truck. Would you please verify if in fact this product has the wide rails for the previously mentioned truck

Expert Reply:
If you have a 5-3/4' bed on your 2021 GMC Sierra you have the narrow rail option of the RetraxPRO MX # RTX77FR and the wide rail option # RT80471. If you like the wide rails but want to make them functional since they cover more of the stake pockets, you can get the RetraxPRO XR # RTT-80481 which gives you accessory T-Slots to add things like this Yakima Overhaul Ladder Rack # Y01151-5855.
