Not sure I agree with everything you say. You can get F150s that are rated over 10k#. Not that I would consider towing that with a F150, but, say, 7k# is perfectly reasonable. My Expedition is rated at over 9k#...wouldn't consider more than 7k# in that, either. I regularly tow my 6,500# travel trailer over the mountains and other than having to shift into 2nd, there is no ill effect. I have well over 2,000 miles on this combination....anything over about 5000 lbs is in 3/4 ton range...Can a grand cherokee handle 800-1000 lbs tongue weight?
Of course, on the other side of my mouth I politely offer that my NEXT tow vehicle will be a 3/4 ton. Half to make the towing experience a little easier, and half to take full advantage of my 10k# rated utility trailer.
Also, I'm not sure of your tongue weights. Handling a tongue weight is a matter of structure. Any thusly rated hitch can "handle" the weight. Your question is probably more toward the suspension squat.
While I 100% believe (along with Chris and others) that a WD hitch IS NOT intended to "hide" an overloaded tongue, it IS intended to work in conjunction with the truck/hitch/trailer to maximize the tow rating. Without looking, I will guarantee that the Jeep specifications stipulate that the full tow capacity is only achieved with a WD hitch. Without one, my truck (for example) is only good to 6k#.
Having said everything I just said, I am of the opinion that a Jeep Grand Cherokee shouldn't tow more than 5k#. Wheelbase and truck width will bite you every time. As I said before, my 1/2 ton body-on-frame truck has no business towing more than 7k# for any appreciable distance.
So to generally summarize my reply to Mr. Dirtyoldman's point and my opinion in matters of ROUGHLY gee-whizing long-distance towing capabilities:
-Jeep/uni-body/sub-half-ton-whatever: 5,000# max
-Half-ton trucks/SUV's: 7,500# max
-3/4 ton trucks/SUV's: 10,000# max...maybe a little more
Of course, I'm much assured that others will have strong opinions to counter the above. These are just my mental rules-of-thumb having wandered around the Travel Trailer world for the past couple of years.
