How Wide Are Rails for RetraxPRO MX on 2022 GMC Sierra 3500

Published 08/26/2022

Question:

I am considering the RetraxPRO MX Hard Tonneau Cover # RT80485. It has a really low profile for my gooseneck trailer. However, my last trucks tonneau cover had rails that came inside the rails by about 1-1/2 inch to 2. That ended up limiting my turn angles with the hitch yoke on the trailer. Is there a tonneau cover with a limited height profile AND either a small inside the rail footprint or sits on top of the bed sides?

The RetraxPRO MX Hard Tonneau Cover # RT80485 is going to take up about 1" of space of internal space on your 2022 GMC Sierra 3500 truck bed according to my contact at Retrax. This shouldn't interfere with a gooseneck hitch or pin box unless you have a uniquely styled coupler that is longer than the standard.
