I checked with Demco and their Tabless Base Plate Kit item # DM29FR is exactly what you need to flat tow your 2023 GMC Sierra 1500 with a Excali-Bar III Tow Bar item # DM9511013. This is custom fit and works with all models of the 2023 Sierra 1500 including your AT4.

Here are some other parts you're going to need to flat tow your 2023 GMC Sierra 1500:

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

Battery Disconnect Switch - Roadmaster Battery Disconnect with Switch for Towed Vehicle item # RM-766

Supplemental Braking System - SMI Stay-IN-Play DUO Supplemental Braking System item # SM99251 or item # SM99243 if your motorhome has air brakes

Brake Light Switch - Roadmaster Stop Light Switch Kit item # RM-751495

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.
