In 2003 Ford released a limited production “Heritage Edition” trim package as part of its 100th Anniversary celebration, and there were 15,000 of these models produced. This model had a two-tone paint scheme and other special styling differences that set it apart 
from the other F150 models. A picture of one of these models is shown to the right.
There tends to be confusion when talking about the Heritage, though, as there is also a 2004 Heritage (not Edition). The 2004 Heritage is actually just a 2003 F-Series that was carried over into 2004. There is no special branding or code associated with it as it was not a special trim package, but merely a run over from the previous year. So even though you purchased a 2004 F-Series truck, you could have either a 2004 Heritage that has the older body style (1997-2003), or one of the newer body style (2004-2008) trucks. When ordering parts, please double-check the year and the style to make sure that the parts match your truck.
Are the “inner rockers” something that is always rotted out when the outer ones are? I have an ’02 with totaled outer rockers but the inner ones look like they were galvanized and show no rust whatsoever.
Hi Mark. The inner rockers usually rust the same amount as the outer rockers, but not always. We’ve seen a number of trucks where just the inners or just the outer rockers needed to be replaced, but not both.
