My bad for not updating.
We have pulled the 2013 Lincoln MKX for several trips now. The first trip was a little exciting when we stopped. I started to unhook, tried to start the car and nothing. Starter would not engage. To make a long story short, the installer of the AF1 reversed the polarity on the indicator light that tell when the car brake pedal is depressed. Replaced the fuse under the hood and poof, magically it started. I have since corrected the reverse polarity.
All tows so far have been good. I did not need a drop/riser receiver as it is well within specs. Maybe something to do with having the 22.5 inch tires on the MKX.
I did purchase the Kar Kaddy (sp) from Blue OX. Unfortunately after 4 or 5 tows it has started to come apart at the seam at the receiver end. I have sent an email to Blue Ox but no reply yet.
I follow the manual for towing. Run for 5 minutes before towing, drive, neutral, reverse, back to neutral, turn off AC and entertainment syste, place ignition (keyless) into accessories status. I also turn off the console display screen, and I put the alarm system I have into valet mode.

It is what it is, and then it is what you make of it.
