Hey Kevin, congrats on the new truck! You've done your homework extremely well. I've listed those parts you'll need below out of your list. Let me know if you have any additional questions where it says Reply to Jerred H.

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.

Need approx 20 gallon gravity flow gas tank in bed of my 2023 Chevy Colorado to go farther between stops towing my trailer to Alaska.

@RichardL Hey Richard. There are tanks out there for gasoline but it is not something that we carry. The only one we have that fits your Colorado is much bigger and is designed for diesel fuel. You'll need to find one that fits and is rated for specifically for gasoline.

Not too terribly long ago, Demco purchased SMI. The #SM99209 is the same exact part as the Demco 6271. Same part, different number as confirmed by Demco. We do indeed offer that Spartan-specific Jumper kit as part #SM6296. I've linked you to…

To make a 7-way to 6-way square adapter will require you to get the part #37995 to use the 6-way end and then wire up a 7-way to it like part #H20043. This will give you the adapter you would need since there isn't one already pre-made.
