When you say you slide yours back do you mean towards the tailgate? Do you have the tailgate step?
I did 2 hours of reading last night and it seems everyone that has water issues around the tailgate has the step and due to the low areas where the step is no one has figured out how to stop water from coming in there yet.
I just installed my F1 3 days ago and had some water inside the bed yesterday after driving through a 15 min heavy storm.
