What engine do you have? If its a gasser, you should be able to take it to a local parts store like Advance, checkers, or O'Reillys and have them scan it. If its a diesel, they don't have the right scan tool to get the ford power train codes that diesels have. If you had a program like Autoenginuity with the ford pack you could scan it your self. Is the truck doing something specifically that would trip the check engine light?

No. They do it so they can sell you parts. Same with AutoZone (except California).
Write down the fault code(s) - Pxxxx where xxxx is a four digit code.
Tell them you're going to "check it out".
Leave.
Come back here and plug the fault codes into the SEARCH feature. There are common ones that get asked every week.
If you can't find a relevant post or description, ask (post the codes you have).
