There is nothing on Curt that I can find that looks like the posted crossmember.

I did buy the bracket, bolts and heat shield from my local dealership, $1400, hoping to install this week. I had to find the part numbers, they had no idea what I was talking about. GM is missing out not having a package. Not everyone can just trade in their truck to get a 5th wheel.

Do you have part numbers for the bolts and caps? I just got the system on ebay for $399 but it does not have the hardware.

Great posts guys ! For anyone ordering a new HD, I spent $645 on the factory Max Trailer Pkg.(# NHT). Included, 5th. wheel prep. frame crossmember, holes & plugs in bed, 3500HD Frame, 3500HD rear spring pack with overloads, 12 in. Rear Axel, Rancho Shocks, and in bed 7 way connector. This for my 2500HD. No longer need Firestone Air Bags, like I put on my '16 2500HD for my application. Quite a bargain at $645.

Also opted for the Trailer Camera Vision Pkg. Prep. & Software (# TRG)., with Rear Bumper Camera dual Recpts. in the 7 way connector, Includes Hitch Guidance with Hitch View (#PZ8).

HD Front Spring / Camper Pkg. (# F60) was $45.

I tow a 24 ft. Box Trailer / Workshop to job sites.

Just had to nip back the heat shield where the two arms bolt up to the rh frame rail

Nice job. How do you figure out where to drill out the bed holes? Dykem on the hitch holes to mark the bottom of the bed?

Agargano98 · October 29, 2023

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.

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.

The 5th wheel system is rear of the axle so it will provide enough clearance between the rear of the cab and the front of the fifth wheel without having to use a slider hitch. Typically anyone that tells people on the RV forums that they still need a slider for this new truck will have one for sale or doesn't know how to set up a hitch.
