Expert Reply:

I would be happy to! To flat tow your 2021 GMC Yukon you will need the following parts:

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

Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - Removable Arms item # RM59VR

Battery Disconnect - Roadmaster Battery Disconnect with Switch item # RM-766

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

Supplemental Braking System - Blue Ox Patriot Radio Frequency, Portable Braking System item # BLU37TR

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.
