Hi Winston,
The truck tilt sounds a bit spurious. You must get truck tilt when planting 90.000kgs on a flat surface, I would have thought. It would severly dent the braking performance to use only the rear wheels and proberly necessitate a speedy visit to the pits for a tyre change.
Regarding the single reverser and differential braking; true, but I'd always had the idea that, when there were pedal steering problems it would be better to use autobrakes. That way you concentrate only on steering and not braking. If you have to do both, i.e. apply pedal steering and braking, it is very likely that you'll apply 80% of brakes to the same pedal that your pushing for steering, thus reducing the braking effect. Autobrakes will spread the load evenly and with greater effect.
I heartly agree with the 8000' and reversers idea. If it's not my lucky day and L & R are both useless, I'm off to one of these Space shuttle landing sites.
