Update 2020: I purchased a new 2020 LR+ yesterday, and had a Draw-Tite waiting in the garage. I just finished the installation today. There are some slight changes in the installation, and the manual hasn't been updated, but the changes are easy enough to figure out.
References are to Draw-Tite's installation manual, currently located
here.
Step 3a: These are now 10mm bolts like the others on the underbody
Step 3b: These are a different type of fastener (photo below), and I found it unnecessary to remove them.
Step 3c: I removed a third push pin rivet at the top of the wheel well, which was helpful in getting the liner pulled back.
Step 3d: On one side of my vehicle (passenger), the yellow plastic nut that holds the screw spun freely and was very difficult to lock. I wound up raising my suspension to Very High and using a pair of vise grips to hold it in place. Same for putting it back together. Be careful, the car may not stay in Very High suspension, especially if you close the door and it locks.
Step 5: I performed this cut, but after reinstallation realized it was unnecessary unless I wind up hitching something with a very long shank. It leaves a gap behind the hitch receiver, which I find undesirable personally.
I also found that the Draw-Tite hitch receiver was chipped in a number of places. Because we are about to evacuate from local wildfires, and need this hitch receiver installed, I decided to just hit it with a few coats of Rustoleum. The chips were on the edges, and nowhere that would make contact with the X (for fear of galvanic corrosion). I doubt it would have been a huge problem, but I wanted to prevent rust from forming from condensation and humidity.
I still need to fasten the 7-pin receptacle to the underbody panel, which will be done shortly.
Wheel well fastener (anyone know the name of these?):
