You may be able to call call Ford Customer service, have them run the VIN number and they can possibly tell you what came standard. I think you are mistaken on what was standard on the Eddie Bauer edition. I just did a simple search and it looks like even with the Eddie Bauer edition, the things you speak of were NOT standard.
To quote one website:
Options for
Eddie Bauer models over and above those of the
XLT include heated and cooled front seats ($625), new-for-
2008 power running boards ($995), power rear liftgate ($495), a navigation system ($1295), rear-seat DVD entertainment system ($1995), the new rear backup camera ($455), and P275/55R20 tires.
another website showed Ford's ad listing (
https://www.autoblog.com/buy/2008-Ford-Expedition-Eddie_Bauer__4dr_4x4/reviews/), it read the following:
The Eddie Bauer ($35,865) and Eddie Bauer 4WD ($38,675) are trimmed as outdoor adventure vehicles and are distinguished by a longer list of convenience features as standard equipment, notably the Expedition's unique power-folding split third-row seat. Other standard features include leather upholstery, 10-way power adjustable driver's seat, six-way power adjustable front passenger seat, memory for the mirrors and driver's seat, dual-zone automatic climate control, an AM/FM stereo tuner with 6CD changer, trip computer, conversation mirror, mirror-mounted turn signals, and protective cladding for the lower body panels. The Eddie Bauer EL ($38,515) and Eddie Bauer EL 4WD ($41,415) are equipped like the standard wheelbase versions but have front tow hooks and 255/70R18 tires instead of 17s.
