What is the difference between the 2004 f150 heritage model compared to say the 2005 model? I am tyring to find accessories and they state that it excludes the heritage model

heritage model is the previous model before the current model change. If youre looking for parts and accesories i suggest you look for 97-2003 parts, theyre the same. Heritage F-150 refers to previous model leftovers on the lot and the plant. Hope this helps you out.

I just purchased a 2004 f150 and was looking for aftermarket nerf bars to install and i kept finding this answer in my searches. Defining what a heritage model is didn't help me in figuring out what to look for to determine if mine is the heritage model so.... A 2004 F150 heritage model can be identified from the 2004-2008 new body style by 2 things. 1- Rest your arm on the door. if your arm is flat, you have the heritage model, if there is a large ~2" hump halfway across the surface such that your elbow is higher than your hand, you have the new body style. 2- Look at the front bumper where the fog lights are. The heritage model has a hump where the bumper meets the grill, the new body style is flat as in this picture: Cheers!
