Just bought a new tow vehicle. 2013 Suburban. Its got the factory trailer brake controller on the dash. Anybody out there with a newer GM using the integrated trailer brake controller to pull a trailer with electric over hydraulic brakes? The manual says "connecting a trailer with surge,air or elec over hydralic trailer brakes may result in reduced or complete loss of trailer braking". WTF...... one of the reasons I bought the SUV was for this feature. It states the controller is for electrical brakes. Anyone out there with a newer GM who's got experience with this issue?
