I am suffering from the same issue with lots of rain recently, have an appointment at my local dealer coming Monday, it's under cpo warranty and I also brought the extended warranty so I'll see what's will be the outcome after I brought the truck in.
Stick them to the CPO.
Extended will most likely not cover jack, as far as I have read here.

Did you go far enough left and right and did you put in enough to really fill the space? (I ended up using almost two tubes)
If so, then the brake light would be my next target.

I think I need more on the outside, but I put clear silicone in the crack between the plastic and metal from the inside. I think that's where it comes in?

The third brake light has flex seal tape inside and outside. No way it's coming there.

Really hope I don’t get this issues I have a 22 Laramie as well and I can tell you I wouldn’t be happy if this happened on my brand new truck.. keep us posted though whatever has worked for y’all.

Found a couple drops on the window after work. Grabbed some black sealant from home Depot and filled the corner of the window where the plastic guides are. This needs to stop because my wife is beginning to mock me and say I should have just taken it in.

Yeah...and if you can't get it to stop I can't imagine the dealer will cover it now

I didn't want to take it to them anyway. All I've read is they put a band-aid and people end up getting leaks again.

So is the consensus that 3 tubes of the 1.5 Oz Permatex will do the top and sides?
Is this stuff to runny for the sides or do I need to make a dam on the sides to keep it from running out and down?
