2000 SIlverado 5.3
Lots of Miles lol

Noticed a fuel smell when leaving for a 3 hour road trip today. Thought i was neighbor. Got to my destination (with no excess fuel usage) and smell was definitely my truck. Look under and the fuel tank where it meets the cannister was dripping fuel (slowly)

Went back out 5 min later and it was dripping. But obviously wet and still smells. See picture. Is this a culprit of a vapor cannister or do I need to look further into it?

Not sure about your pump; but the next gen trucks are prone to fuel pump leaks.
It's in the output line, the short piece that comes out of the pump, only repair is a new pump.

A couple of years ago, I had the same problem and It was the leak I described above, it would wet the top of the tank and maybe start to wash over the side of the tank; but never reached the point of dripping.
Mine started in the winter and I waited for warmer weather to drop the tank and fix it, so you should be fine. But, of course, all leaks are not the same and it depends upon the flow rate. If the leak gets big enough the engine will quit.
Mine was just a very small rust pin hole.
