100% agree with this. Luke at Truck Alterations got me mine for $675, as well. Got it in 2 days. No complaints with the cover. I haven't noticed any leaks.
I ordered the Lomax TriFold from Truck Alterations Tuesday afternoon at about 4:00. I went home for lunch today and it was being delivered at about 1:00 today (Thursday). The price was still at $675 shipped with no sales tax. Luke was awesome to work with. Now I get to install it tonight!
I just traded emails with Luke. He is still at $675 with free shipping. That is over $200 less than everyone else. Everything good when you dealt with Luke and truckalterations.com? Is that cover easy to remove if you need access to the entire bed? I assume it is but would like real world experience.
I have this noise on my 2019 Sierra, as well. I thought it was just me being too damn heavy! I get it when going over big bumps, too. Curious to see if there is any fix to this.
I get this from time to time. I will start the truck and it will be on and then turn off a few seconds later. I have used the settings to make sure the volume is at zero every time that I start the truck. The volume being on probably happens once a week or so. All the other times it is at zero. I just looked at my build sheet and I have an "IOT" radio.
I found the manual online so I was probably wrong on the page number. Sorry about that. I should have walked out to my truck and grabbed the manual. I hope it worked for you this morning.
There is a setting in your menu on the infotainment system. It is on page 95 of the Infotainment System User Manual, for your reference. It is under Settings and "Maximum Startup Volume." I was annoyed by this as well. I adjusted mine down to zero.
Just got back from the dealer. That took almost 2 hours and I even told them where the rattle was coming from. They were able to replicate the rattle, so that was a win. Then they took 2 headrests from a truck on the showroom floor and put those in mine. Apparently, the rattle disappeared. They ordered me 2 new headrests. So, now I wait.
Just thought that I would followup in case it helps anyone else.

I am new to the forum. I picked up a 2019 GMC Sierra SLT a couple weeks ago and had this rattle almost immediately. I tried spreading the posts apart but it didn't seem to work. If I take them completely out, the rattle stops. I have an appointment at the dealer over lunch today. I can't wait to hear what they have to say.
