The GMC Terrain models from 2014 through 2016 can call be flat towed four wheels down, but it is recommended to have a speed restriction of 65 mph on all of these models when doing so. It is also recommended to start the vehicle and let it run for 5 minutes prior to towing and at each fuel stop. This gets the moving components properly lubricated to prevent damage. You will also want to let the engine idle for 3 minutes or more prior to driving after towing it. You will also want to remove fuse 32 while towing to help your vehicle battery from draining too low.

The SMI Air Force One Supplemental Braking System for Motor Homes with Air Brakes - Proportional # SM99243 is an excellent option that is a confirmed fit on these vehicles. I've attached a video of the similar Chevy Traverse install to assist.

If you have further questions, please let me know.
