Thank you so much. That’s it to a “T” . Really appreciate it

19 GMC Sierra AT4 here. Had the leak, took it to the dealer and they seem to have done a good job fixing it from a leaking perspective. My problem now is the noise from what I’m guessing is the spoiler. In the cold temps it cracks and pops like crazy. No difference in noise when going over bumps, etc, just temperature fluctuations. It’s driving me crazy. Going in to the dealer in March, will have them look, as I’m still under warranty. Mostly wondering if anyone else had this happen, and what the fix was. thanks

Got mine back from the dealer. Very happy with the work that was done. Did a thorough leak test, and bone dry on the inside. I will keep a watch on it, but I’m hopeful.

Mine goes back in to the dealer tomorrow. I took it there after telling them the problem, last week. They called me first thing in the morning and tell me there’s a TSB for that problem (no kidding) and they have to order bolts. So I drove it in there, left it overnight for them to do that!!!!!?!??!. Anyway, bolts are in. Getting “fixed” tomorrow. Why do I get the feeling this is the beginning of a long painful saga? Hope I’m wrong. Sent from my iPhone using Tapatalk

My 19 AT4 goes in this Friday. I can only hope for that level of service. Fingers crossed. Sent from my iPad using Tapatalk

That’s exactly the situation I have. I will try that. Did you apply the sticky side towards the bed, or use the sticky side on the underside of the liner? This is the first time I’ve had a tonneau cover. I was worried about adding a bunch of extra foam then if I need to remove the cover to haul something large, having to re-do everything. That may be the case, but if there’s a way around it, I was hoping to learn. Sent from my iPhone using Tapatalk

Thanks for the suggestion. Being the new guy, I generally try to tread gently, but I don’t see anything in that thread regarding tonneau covers. Sent from my iPad using Tapatalk

First off, let me say that I have been lurking here since I bought a 2019 GMC Sierra 1500 AT4 last week. What a wealth of knowledge here. I sold my 03 Silverado, and bought the GMC. Loved my 03. Running like a champ after owning her for 18 years. Hope I get similar life out of the GMC. Today I put a Truxedo Lo Pro tonneau cover on the truck. No problems putting it on. I decided to test it for leaks so I put the hose on shower and simulated some rain. Pretty good, except for small leaks at the corners near the cab. Has anyone had this, and what was the best way to fix it? I think if I seal the corners, it will be pretty dry. After reading all of the posts on here regarding leaky rear windows, I figured” what the heck” and threw some water on the cab. Of course I had a leak from the drivers side corner of the rear window. It’s a slider, for anyone wanting to know. My question regarding the infamous leaky window, is, what is the fix from the dealer? A gob of silicone, window replacement, or just luck of the draw with the dealer? How have the fixes been holding up? Slightly frustrated, but not really surprising after reading about all of the leaks on here. Sent from my iPad using Tapatalk
