Thanks guys for the information. I ended up getting a Lincoln Navigator L ultimate. Very nice overall. Hopefully, the backup camera available in 2008 will be a plug-and-play, but I won't hold my breath.
As far as the 120 V power outlet, I did find a nice unit at Fry's for $29. As much as I love the new ride, I find it amazing that across all the large SUV offerings, the higher-end minivans run circles around SUV's in most applications, functionality, creature comforts, storage compartments, cargo space, interior versatility.
