I have an 04, v8, AWD and unless you're vechcle is considered "severe service" there are no major required services until 100K.
Note: service service is described as:
heavy city traffic where the temp reaches 90 or higher (Fla?)
hilly or mountainous terrain (def. not Fla)
frequent trailer towing- (transfer case fluid change at 50K)
taxi, police, or delivery service.
If your driving falls under this cat. you essentially do the 100K service at 50K
Maint schedule should be in your owners man- sec. 6
