Seeking GMC22 2500HD suspension/drivetrain specs

Hello folks, Happy New Year!

I am trying to identify OEM specs or limits in my 2022 GMC 2500HD Gas single axle truck. I am purchasing a truck camper and due to those weights found I must add some upgrades but first need to know the OEM specs. In an auto trans, what company mfg's the axles, PN, and better yet, the load specifications. Same can be said for the wheels and springs. Any other load limiting parts? Feedback is well appreciated.
