Yeah, mine is an 2008 LE and the info is printed on the Factory Window Sticker, not the add on dealer sticker.
Also, what made me more suspicious is that there were scratch marks on the bolts and metal plates that secure the mirrors to the door.
Like I mentioned earlier the dealership has a bad reputation, only reason I bought my truck from them is b/c they had 20 on their lot and after 4 hours of negotiation I walked out with a deal.
Also, I have the memory seating function which is suppose to control not only the seating position but the mirror position and guess what? The mirrors do not return to the set position but the seats do? Go figure?
