We tow an Explorer Limited 4x4 with a Falcon All-Terrain, and use Roadmaster's Brakemaster. Not an iota of a problem with the Brakemaster system. Sometimes the towbar is hairy to crack loose upon disconnect if the car is at a strong angle or grade; even the so-called anti-bind lever release system can be stubborn. But the Brakemaster and neutral tow kit work okay for us. You just have to remember to double check the parking brake is released, as with any tow system, and make sure the car windows are closed, cuz in the recent spell of heat I often forget, then have to undo the neutral tow settings to get the ignition switch to the "ON" position, roll windows up, and reset the tow.
