Got this from Nissan this afternoon:
"Thank you for taking the time to personally contact us about your interest in Nissan products.
The Off-Road Package has been taken off the website to avoid confusion because the electronic locking differential is to be added in the coming months which will change the pricing of the package as a whole. Again, thank you for your interest and patience concerning this matter.
We hope that this information answers your question, but if you need any additional information or have further questions, please let us know by reply e-mail or by calling 1-800-647-7263 and pressing "0" for a live operator.
Also, make sure to take a look at our website,
www.NissanUSA.com, for the most up-to-date product information.
At Nissan, we are committed to a high level of customer service.
Sincerely,
Nissan North America"
