So, I'll enter the fray...
After reading the original post, I checked our store display CA-4 caboose, sitting behind our VL Big Boy. Well, yeah, the coupler's a tad low, but nowhere as misaligned as in the OP's photo with the reefer. Maybe the reefer has a coupler problem, too??
But what we have determined on the 'boose is that the spring tension on the center rail pickup roller is horrendously stiff!!.....and this exacerbates the problem by causing the truck to tip, placing the coupler at either end downward. And when you have the extra long bar length for the coupler on a caboose like this, any downward tip of the truck is magnified. In fact, I believe the roller is actually lifting the inside (roller end) wheel axle off the rails due to its stiff spring tension!
Even so, holding the truck mounting to the body securely, the sheet metal arm that is part of the extended coupler reach is loose in its fit to the truck frame....I'd say about 3/32" to 1/8" vertical 'slop' at the end of the knuckle.
Ergo, we assess two problems with the truck design: Roller pickup spring way too stiff, and the extended coupler arm too loosely attached to the truck. But, that's just OHO.
As for the LED vs. incandescent lighting, and other catalog/website description anomalies...c'est la vie. The ubiquitous caveat: "Items depicted in this catalog are subject to change in price, color, size, design, and availability."...is on the catalog(s) in question...I just checked. I'm sure that, as we speak, flagellation and water-boarding...and a measure of apologetic regret...of appropriate parties over this latest set of problems is quietly taking place.
Dang, I'll bet Lionel wishes they had a remote control device for their manufacturing/quality control efforts 12,500 miles away that's as effective and exciting as their Lion Chief Plus remote control of choo-choo trains.
Problems, problems, problems...
