Why does my truck tremble when at a stop?

Question

I have a 2001 Ford F150 4.2L truck with 125k miles. When i am at a stop my truck trembles a little bit. The tremble isn't constant it will tremble then stop then tremble again and so on until i drive off. It has being doing this for a few years now. I also hear a rattling sound under the truck when i press on the gas. It is not loud but sounds like something is loose.
