Here are the parts you need to flat tow your 2026 Chevrolet Colorado ZR2 behind your 2022 Entegra Cornerstone:
Tow Bar - Roadmaster Nighthawk All-Terrain Tow Bar w/ LED Lights item # RM-676
Baseplate Kit - Roadmaster Direct-Connect Base Plate Kit item # RM28GR
Wiring Harness - Roadmaster Universal Hy-Power Diode Wiring Kit item # RM-152
Charge Line - Roadmaster Battery Charge Line Kit Item # RM-156-25
Battery Disconnect - Roadmaster Battery Disconnect for Towed Vehicle item # RM-766
Supplemental Braking System - Second Vehicle Kit for Demco Air Force One Flat Tow Brake System item # SM99209 and the Air Force One Air Jumper item # SM6296 and the Demco Wireless Coachlink Braking Monitor item # SM99945
You do not need the RoadMaster 6-Wire Trailer Connector item # RM-910030-7 as it comes with the Nighthawk tow bar.
Do you have a high-low adapter? If not you may need one depending on how far off the ground your motorhome's hitch sits.

Hey Kevin, did you end up needing a high-low adapter for your setup? I'm curious to know how everything worked out for you, as it could help others planning a similar towing setup.
