Expert Reply:

To flat tow a 2024 GMC Sierra 2500 you will need the following parts:

Tow Bar and Safety Chains - etrailer XHD Non-Binding Tow Bar for Direct-Connect Base Plate item # e84ZR

Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - Removable Arms item # RM33GR

Battery Disconnect - Roadmaster Battery Disconnect Switch item # RM-766 for gas or item # RM93MR for diesel

Wiring Harness - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267

Supplemental Braking System - SMI Stay-IN-Play DUO Supplemental Braking System item # SM99251 or item # SM99243 if your motorhome has air brakes and the Roadmaster Stop Light Switch Kit item # RM49GR

High Low Adapter - The tow bar needs to be within 3" of level. If you measure the height of the inside top of the hitch receiver tube on your RV, and the height difference is more than 3 inches above/below the base plate tab height, you'll need a high/low adapter. I have linked a FAQ article that explains all this in more detail along with our selection of adapters.
