I got rid of the F150 and went back to a SD again. The first thing I bought was another Eagle cap. No leaks or any issues so far. I have to tilt-in front glass so I can clean the cab back window and no leaks there either. My neighbor just bought an F150 about the same time I got the SD and he also went with a Leer cap against my advice. It looks nice. I'll have to ask him about any issues.
