Did you see a reason why you couldn't have turned it 180° to get it over the axle like a long bed?

 

I read it was because of a crossmember. I don't see it from your photos. 

 

Then I read it was for turning clearance with the cab.

If you look at the hitch there is a u channel in front of the ball mount.  This is for clearance for a stiffener on the underside of the bed itself.

So I found a factory GM Puck system and used the above measurements and I am very happy with the install. I appreciate everyone who posted, it really made the job easier.

did not add it   but rather ordered it....   I think the challenge will be the puck system... getting that added.

A BED crossmember. I didn't see that coming. Thanks.

Did any of you get a wiring harness to put the 7 pin connector in the bed or are you just using an extension? If you did, do you have the part number for that? I know there are lots of generic kits but I want the camera plugs in the bed along with the connector.

If you don't want to go through GM for the parts you can also shop etrailer.com. They have the hitch, wiring and video instructions online.

You need the following parts:

 

- 84663240 harness extension 

- 84670050 harness Y-cable

- 84056018 7-pin/4-pin trailer hitch receptacle 

 

You unplug the connector from the bumper trailer hitch receptacle and plug it into The y-cable and insert the other end of the y-cable into the bumper trailer hitch receptacle. The third end of the y-cable plugs into the harness extension and the harness extension plugs into the trailer hitch receptacle that goes into the bed. There’s a plastic cover you remove from inside the bed and press the trailer hitch receptacle into.

The 7 pin connector in the bed has a 4 pin trailer connector integral with it.  The camera connections remain with the external 7 pin connector on the bumper.  At least that's the way my 2024 LTZ is rigged with the 5th wheel package from the factory.

Straight edge across the bed mount holes, measuring forward, and measuring multiple times.  Hopefuly when i get the bed back on tomorrow its good.  Should be fine as the factory covers are oversize to the hitch.

What size holes need to be drilled in the bed for the puck covers? Are they the same size for the gooseneck puck and the 5th wheel picks? Or are those different?

They are different, don't remember exactly what size offhand.  And the 4 puck holes are oval, so I double drilled with hole saws and used a small cut off wheel to cut out the middle.  I just used the caps to get the hole sizes.

Does anyone know if there is room on the frame to mount a 5th wheel rail kit to a truck that already has the prep package? To use the prep package I need to use the Demco 6333 adapter to fit my Andersen hitch. That adapter is about 2” tall. I am pulling a 5th wheel designed for a 1/2 ton, typically a lower truck, and with the height of a 2500, and then the height of the Demco adapter it may be too high for my use. The rails that you just bolt down with frame brackets are only 1” tall. Just curious if anyone knew……I guess I could try 1-2” drop shackles but will that void a warranty?

I don't think it's going to work. I just went through installing the OEM puck system on my truck this weekend, and there likely isn't enough space (front to back, not side to side) between the 5th wheel pucks and the center gooseneck puck for the rails to fit between them. The no-drill style under-bed brackets probably won't line up with the holes in the frame either, so you would probably need to drill into the frame to finagle something.

 

What about swapping out the Andersen to one of their gooseneck mounted hitches? I know that the standard one is taller than the rail version, but they also make a lowered flatbed version that is lower profile.

I was eyeing up the lowered flatbed version but they told me that it would be too low and my trailer would make contact with bedrails. I’m thinking it may work with the ball in the highest position. That is always an option for me as well if yep they will let me buy one and return it if it’s too low. My 5th wheel is an Escape 5.0TA designed for a 1/2 ton but I wanted a 2500 and seeing what I need to do to make it work. Thanks for the info! 
ohh, the height of my Andersen rail mount version and the use of the Demco 6333 adapter should be about the same height as the Andersen gooseneck ball hitch. So yeah, the lowered flatbed version may be worth a try with the ball in the most upright position.

Finished up my installation this past weekend. I went to a dealership and took some measurements from a similar truck with the puck system installed.

 

Here are the measurements I used for the holes:

Here's how the holes turned out:

Pretty much spot on.

 

The gooseneck hole is a little too big for the OEM cover. I used a 4 inch hole saw. Probably 3.75" would have been better. I also only cut circles for the 5th wheel pucks so far (those I cut 3.5 inch holes). I am going to try using the Ford style covers. I have an extra set from my F350. I like those a lot better than the GM covers. The GM covers seem like they would get dislodged pretty easily. Plus you have to cut notches into two sides of the holes for covers to lock into. Otherwise the will be too big and won't sit in the holes nicely.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.

      No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.

      - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.
