I feel like an idiot but one MAJOR issue I didn't factor in when trying to figure out how that rig could be so much less stable than what I experienced with my LR3 w/ similar rig is the distance from the rear axle to the hitch.
The rear overhang on the expeditions is EXCESSIVELY long. The departure angle performance on the LR3 require a very short overhang (even w/ the relatively short wheelbase for break-over performance).
In any event, I'm sure someone better at math / geometry could figure this out, but just based on side-shots, it appears that the leverage factor involved with such an overhang is pretty severe for this weight/size TV; both vertical forces and clearly lateral as well.
On the other hand, I'd imagine that the short distance on the LR3 mitigates the short wheelbase entirely and bumps up the handling quite a bit. The other issue is how much that leverage acts on the front suspension, steering etc. Any bump and subsequent downforce on tongue would tend to lift the front end off the ground, or at least lighten the steering a lot (which would get really sketchy at those speeds). Again, conversely, when your load is close to the rear axle, the moment arm will be much different and won't act on the front of the vehicle (rear/fulcrum will tend to carry most of the load). NOW I can see how not having air suspension would be even more of an issue, as that's a lot more force on the suspension w/ that overhang.
I mean just looking at side-shots of the Expedition overhang.. doesn't take much imagination to see how the tail could wag the dog BADLY.
