Slide awnings are not designed to prevent water from entering the coach. They are simply there to keep debris...leaves, pine needles , etc...from getting under the rubber flap when retracting the slide. So I wouldn't be concerned with those.
You mentioned you caulked around the slide trim. I found my Miramar was leaking slightly when tilted with driver/slide side up due to inadequate caulk around the lower facia trim of the slide. Water would leak in and get between the water proof undercover of the slide and the slide floor itself. When the slide was extended it would seep outside so it only appeared when the slide was in.
If you are certain that is NOT your problem then it has to be your rubber wipes and/or bulb seals. If you can extend the slide and see under the awning you should check to see if debris is preventing it from doing its job. If you find nothing there you should treat the rubber per instructions. I use this:

Any good treatment will work and you can find many online.
There are other possibilities to the leak but I think what I've mentioned are most likely.
