Expert Reply:

Congrats on the new truck William. The correct baseplate for your 2026 Canyon AT4 is the Roadmaster item # RM48GR. Unfortunately, you're going to need to buy the entire kit with new arms. You can't just buy the parts that connect to your Canyon's frame separately. Hope that wasn't the part that made you angry with the Roadmaster Rep. This kit comes with all hardware you'll need to complete the installation, along with a bracket to mount the 6-way connector.

I linked an installation video below along with a couple of pictures so you can see how to get the item # RM48GR installed and what it's going to look like when you get it all set up.

Here are the rest of the parts, I recommend using to flat tow your 2026 Canyon AT4:

Tow Bar and Safety Cables - etrailer XHD item # e84ZR

Battery Disconnect - Roadmaster Ace Battery Disconnect w/ Key Fobs item # RM39ZT

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

Wiring Harness - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267 or just the following parts if you already have the 7-way to 6-way cable.

Roadmaster Universal Hy-Power Diode Wiring Kit item # RM-152

RoadMaster 6-Wire Trailer Connector - item # RM-910030-7
