Hello all, I recently added a 2015 Explorer with Factory Class III hitch and have questions about towing a vehicle. I have delusions of driving a Focus on a race track (actually, I've done it several times) and would like the option of towing the Focus there, rather than driving. As I see it, there are 2 options: a dolly and a hauler. From my understanding, the explorer that I have can tow 5k lbs - so a 3200lb car and a 1k lb trailer is within capacity. I would need a weight distribution hitch, correct? Now with the 52T package, I can plug the wires from the trailer into the back of the explorer and the lights on the trailer would work. I am assuming there are brakes in the trailer - but what if there aren't? Will the Explorer I have be able to handle the additional weight? How are those brakes engaged? The 52T package comes with Sway control - does that matter? What do I need to know? Thanks!
