Crazy issue with Brake Controller/system - Need Advice

It's really not. If it's raining you need to back it off. If the trailer is appreciably lighter or heavier with water and other junk it will need adjustment.
Of course, if nothing ever changes then the controller can be left alone.

If it is raining, I would hope you wouldn't hit the brakes as hard, therefore the trailer brakes don't brake as hard. Likewise, a heavier load requires a bit more braking and that too is done with your foot. A good controller doesn't need to be fiddled with at all.
