To flat tow your 2023 GMC Canyon Denali with a 2017 Tiffin Allegro, I recommend the following parts:

Aluminum Tow Bar and Safety Chains - Roadmaster Sterling Tow Bar item # RM-576 and item # RM-674

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

Supplemental Braking System - Demco Air Force One Supplemental Braking System w/ Wireless Coachlink item # DM26VR

The Demco Air Force One Supplemental Braking System for Tiffin Chassis Motorhomes w/ Factory Air Brakes item # DM55MV you were looking at works with the Tiffin motorhomes manufactured after 2020.

You will also need a baseplate, wiring harness, and potentially a high low adapter. The best options are listed below:

Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - Removable Arms item # RM48GR

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

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.

Yes, the Demco Air Force One Supplemental Braking System #DM55MV does draw from the towed vehicle battery. Installing a charge wire for the battery would be a good choice like with the part #RM-156-25 to keep the battery topped off.
