Hello,

New first time owner of GMC Sierra 1500 Ultra Denali Carbonpro.  Looking for suggestions for Hard tri-fold tonneau cover. Also, need good instructions for installation and preferably a detailed step by step video.  The truck will be towed behind our motorhome, so the tonneau is pretty important to keep road grime, gravel and weather out.  Any help is appreciated.

Thanks

Welcome. I’m a newbie too. Got a 21 also. Check out your local Leer or whatever truck businesses. Leer installs caps, but they have a vast array of tonneau covers.

Thanks for the advice, Morgan.  Most of the dealers I have talked to have not installed tonneau covers on the Carbon Pro box.  Some have said they would need to drill into the carbon fiber, and that is something I don't want to do.  I have been talking to Weather Tech about their alloy tri-fold tonneau.  They have a j-clip system to secure the side rails to the Carbon Pro box on my Sierra 1500 Denali.  I am now waiting to receive it and will try to post some pics when it is on.

OK, got the Weather Tech Alloy Tonneau cover.  My wife and I installed it in approx. 3 hours.  We are both 70 years young, and although a bit rough on the knees and back, we had little trouble.  The "drill guide" provided by WT as a bit difficult to maneuver into the correct hole, as there are the square holes in the carbon fiber next to the round holes that need drilling through the plastic cap.  Once we figured out how to get the guide in the right place, the process became easier.  The "U" clips went in through the existing square holes with a little extra effort from a flat head screwdriver to line up with the round holes.  The side rails went on pretty easily, but the bolt heads were to close to allow my sockets to fit.  I had to use the open end 10mm, which added to the time required.  Installing the  cover was a breeze (I did that by myself under my wife's careful observation.)

BTW, rained pretty hard the night after the install.  Interior was dry.  Drove through rain storm next day and bed was dry.  So far feel good about this cover.

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.
