I am not trying to argue the Discovery is suitable, but hopefully shedding some light on why it is stated.
My father-in-law owns an F150 and his model is not far off the towing capability of the Discovery. That surprised me.

I find your post sort of interesting. Virtually every unibody SUV manufacturer (small/midsize) precludes the use of a weight distribution hitch. It's not because of an air suspension, it's because a unibody cannot withstand the stress that a wdh will put on that type of body construction. Been that way for as long as I can remember. I would never argue about the towing abilities of a Disco either....they can't.
