Hey Mark, we have the RetraxPRO MX part # RT80485 that is a confirmed fit for your 2024 GMC Sierra 3500 long bed. The fit of this is not based on the OEM puck kit as that would not affect anything related to the cover. Are you wanting to cover a fifth wheel hitch when not towing?

Yes. It is a Curt PowerRide 5th Wheel Trailer Hitch for Chevy/GMC Towing Prep Package - Dual Jaw - 30,000 lbs.

@MarkL Makes sense! How do you like the Curt PowerRide # C36WR?

@JamesonC I ordered it through etrailer, as I do all things towing and it will arrive 28 November, but your last reply did not answer my question. Will the Retrax PRO MX close over the hitch as needed. I need to know that that hitch will sit low enough. Thank you.

@MarkL Sorry about that! Yes it will close over that hitch. Since it's handle does not stick up a lot higher than the hitch head there won't be any issues. I wish I could upload a picture here as there is a picture I found that shows a similar tonneau easily fitting over that hitch.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Hey Jerry, GM moved the placement of their puck systems starting with 2020 models so you are correct that the pucks would have the hitch not sit directly over the axle. GM did the math and made sure that this placement wouldn't adversely affect…
