it might be time for a new car

[JThiessen]

Due to the fact that you are heading into college, you should keep the Ford. Its a win-win for you. Any college student that goes in with car payments, and possibly high insurance payments, is going to struggle.
Cars are the worst investment you can make (unless your talking about classic's). I know for a fact - I've been deeeeeep in that hole, an dit took many, many years for me to get my head above water on them.
The trucks value is going to plateau for a while - keep in decent shape, and when you are done with school, you can then pick out a brand new vehicle, and sell this one for almost what you can get for it now. If nothing else, you can put some money into it (dont do a lift - they actually bring down the value, and add to your maintenance costs).
