airstream ride?

TorFlex axles don't suffer from bump steer like hung axles. This feature would probably reduce the "tail wagging the dog" syndrome. and result in a smoother tow.

If your truck hurts her back while empty I would agree with the post about upgrading her seat. The next step is upgrading the truck. My current Dodge is a nightmare compared to my previous Titan in terms of ride comfort. Probably a result of completely different capabilities.
