VIN Number Breakdown
I'm in the market for a new truck and want to get an '02 or '03 F-250. I am looking for specific options plus I'm used to all the ameneties I have in my '97 F-150. I'm trying to find somewhere that has a listing of all the codes for the F-250 VIN number so that I can identify what options are on the truck when I look at them on the lot (surprisingly the salespeople are not so sure about towing packages, gear ratios, brake systems, etc.). I have the shop manual for my F-150 which lists every possible code option but that doesn't help me with the 250's. If anyone can point me in the right direction I would greatly appreciate it.

Here's the VIN Decoder Info
but it won't tell you all the options a truck has. You'll also need to check the door sticker (Info posted separately), between the two, most everything is covered! Good luck in your search
