Hi there, first time posting! We are looking to purchase a T@B 320 S Boondock in the near future and will be towing it with a 2017 GMC Terrain, however the Terrain does not have any braking systems installed in it and we would either have to look for an RF brake controller or we are also considering the Intelli-Hitch:
http://intelli-hitch.com/. We are wondering if anyone has any experience using the latter as we are trying to avoid dealing with any wiring in the vehicle (outside of a 4-pin to 7-pin adapter). Also, any experience towing with a 2017 GMC Terrain? Thanks!
