If you bought it from a dealer ask them to print one for you or send you the file. They can get 'em for no additional charge. That's what I did for mine and I bought my truck from a Toyota dealer!
note this is NOT a copy of the genuine Monroney sticker as original from Ford - it will likely not have line-items which correspond directly to the OE options as shown on a real Monroney sticker
As long as you're okay with a digital version, download the CarFax Car Care app and add your VIN number, within an hour it'll pull the full window sticker for you.
