I have the factory tri fold. The only leaking comes through the car wash. I’ve put down weather strips in the right and left corners. Now it’s minimal.
I had the factory trifold installed. The Car wash causes a leak in to the rear of the bed on both sides. The first time I noticed it, it was enough to soak a cover in the rear. Since then, I've unbolted and reset it closer to the rear window. (There was an overlap).
Then I ran it through again...
I get frustrated when using Car Play, - Waze, podcasts and want to get back to the radio. I just hit the listen button, and say "Sirius radio". then I have the radio!
