I had a leaking problem with my sunroof too. Dealer found and fixed the problem and I have not had a problem since. I was getting water dripping down my back (cargo area) passenger side window, dripping out of the heradliner. Dealer said the drain tubes were not run properly. Apparently there are 4 drain tubes; one runs down the A-pillar (both sides) and one down the D-pillar (both sides). Dealer said one of mine on the back passenger side was not run properly and was draining
inside of the truck. Sounds like maybe one of your front ones might be giving you problems, thus water on the floor.
Good luck !!
