My 21 Silverado RST 5.3L wouldn't start. The starter would crank for a few seconds, but the engine wouldn't start. I had the floor liners out for a good cleaning and left all 4 doors open for about 2 hours as I cleaned my interior. After all the cleaning, the truck wouldn't start. I thought maybe the battery was run down from leaving the doors open, but that didn't make sense to me as the starter motor was turning over. I tried to measure the fuel pressure, but never was able to find a pressure tap. I called the dealer to have the truck in for service and was preparing to have the truck towed in. In my area, the service appointments are 2-3 days out. The night before my appointment, I was searching the web and found a site where someone was listing the top 10 complaints about the GM trucks and one was the truck won't start if the accelerator pedal is depressed. I immediately started laughing my ass off and couldn't wait until the sun came up! Sure enough, the floor liner was touching the gas pedal. After correcting the floor mat placement, the truck fired right up. I don't trust car repair places, and can only wonder if they would have taken advantage of me and soaked me for hundreds of dollars on bogus repairs. The electronics in the truck are pretty sophisticated and delivers a message to the dash when a door is not closed properly and numerous other messages. It is obvious it knew the gas pedal was obstructed. It seems to me it would be easy to deliver a message similar to the "depress brake pedal to start" on the pedal being depressed or obstructed. Simple software feature.

Mine leaks at all four corners. It was installed with all supplied seals. The leakage is worse around the release latch. The latch tang sticks through the rail in a rectangular hole which allows water through. Those who say theirs doesn't leak must have a different tonneau version with a seal around the latch on the left side. The right side also has the same hole without the latch lever. Same problem until I filled the hole with RTV. Any water that gets on the rail will definitely wind up in your bed.

Mine is intermittent. the seal strip on the tailgate is tight fitting and sometimes it takes a couple of button pushes for it to go down and other times it doesn't.

I searched for a few months for sensors because I am a tightwad. No sensors were included with my '21 Silverado, although I had option U1D (the option which includes a module behind the rear bumper to receive the trailer tire sensors). Since I didn't get the sensors when I bought the truck (option PTT), I was told to get them through parts. Chevrolet price is $150 for two sensors. They keep changing the part number every year to confuse us. You can find a set of 4 for $90-135 on ebay. For the '21 Silverado: TPM Trailer P/N 85110397 The manufacturer "Schrader Electronics" for 2021 updated PN (part number) for these sensors, PN 84152501 was replaced with New PN 13540608. I got a set of 84338125 sensors and I can confirm 84338125 trailer TPMS sensors work with my '21 Silverado. I far as I can tell, 84152501, 844338125, and 85110397 are interchangeable.

These are for the 3500HD and a different part number. Are they compatible with the 1500?

Anybody have extra Trailer tpms sensors they want to get rid of? I only need 2 sensors and the cheapest I can find on eBay is about $100 for a set of 4. Otherwise, anyone want to split a set of 4 with me, 2 sensors each? GM TPM Trailer P/N 85110397. The manufacturer "Schrader Electronics" for 2021 updated PN (part number) for these sensors, PN 84152501 was replaced with New PN 13540608

OK, mine telescopes after all. It is a new truck and I had to yank it pretty hard the first time. I feel foolish.

I would like to change my non-telescoping steering wheel/column to one that telescopes. I just can't get comfortable sitting so close to the pedals and need more legroom. Is it possible?

Why not use magnetic mount antenna and take it off when you aren't using it? Magnetic CB antenna at Lowe's

Thanks for the great idea. I was also thinking of putting a plunger switch on the tailgate. I installed LED strip lights in my old Ram and prefer them over the stock GM bed lamps as they provide much better illumination.

Maybe a stupid question, but will this light turn off after a period of time? I put bed lighting in my Ram when I had it and forgot to turn it off one night. Bamm, dead battery the next day.

I installed a new Truxedo ProX15 on an 21 Silverado RST and not happy! I used to have the Truxedo LowPro on a Ram and it had no leaks at all. It is ridiculous to think a $500 tonneau would leak so much. I leaks at all 4 corners. Is there anybody else with this cover able to solve this problem? Yeah, I acknowledge all those who are going to chime in "you should have bought a xxxx" or "I have a xxxx at it doesn't leak a bit".

Sorry for the new post, I found the thread after more searchiing and couldn't find a way to delete my post. (Man, these forums need some upgrades).

I thought I saw in my owners manual there was a wireless phone charger in some of the forward console trays. I was thinking this may be a nice feature to have. Any ideas on an upgrade mod for this?

I am looking at the Lo Pro as well for my new Silverado. I have had one on my RAM for 6 years with no problems at all. I am leaning toward the Pro X15 because of the fabric instead of vinyl. Note that the Truxedo has two different ones for the Pro X15, one with and one without the Mulipro tailgate, but not the Lo Pro. The problem with the Lo Pro is the rubber strip that seals to the top of the tailgate. The rubber seal can sit on top of the tailgate plastic cap or fold down inside the tailgate when you close it after latching the top. I never figured out if you were supposed to latch the tonneau first or close the tailgate first then latch the tonneau.
