Id like to here the pros n cons between the older 5.4s and newer 5.4s. Im thinking about getting a crew cab superduty in the near future hopefully. I like the superduty body better than the newer f150 bodys. Dont really need 2 diesels, thats why im thinkin of a 5.4. No offense to anybody but I do not want nor do I need the v10. Had a 01 crew cab f150 with the 5.4 and I liked it a lot, did everything I needed it to do and I didnt think it did bad on gas at all. Got ride of it, since then I wanted a crew cab since.
