Looking at the picture, I can't tell where the leak is. Everything looks wet. Since the oil was just changed, confirm the drain plug on the oil pan is tight. Also, check around the oil filter for evidence of a leak. They may have double gasketed the filter which will cause a leak
On the 4wd models, there is a remote location for the oil filter. If you look under the center bottom of the truck, you will see a plastic access panel. Open that and see if that is where the leak is coming from.
See pic 1 below for the location. Note that the remote location requires high-pressure lines to run to the adapter for the filter. Inspect them as well.
Let me know what you find or if you have other questions.
See pic below.
