I think what is meant is that QL is available as an Limited option, but only if you don't also want 20 inch wheels. I don't think you can get ORA II and 20s on a Limited from the factory, so there would be extra $$$ involved in swapping wheels. If you want 20 inch wheels and QL and the Tow package, it may be better to look at the Overland. Worth a closer look if you also want QD and the V8.
If you also want skid plates, you have more thinking, but wheels/tires are easy to swap and skid plates easy to add after the fact... your choice.
Best to pick your must have and like to have features and pick the model that gives you the most bang for the buck. It was a little easier when I ordered mine in 2011. QD was only being sold in the Overland. In hind sight, I'm happy I picked the Overland because there were bells and whistles included that I don't know how I lived all those years without
