Why won't a 2018 tonneau cover fit the new 2019/2020 trucks?

Uh, because they are two different trucks with different sized beds.

I'm leasing a 2020 AT4 for only 2 years, and don't want to waste $1K+ for a hard tri-folding tonneau cover. I can get a brand new 2018 cover for around $300, but it's for the previous body style. I've

I know they are different, obviously. im trying to find out where the difference is. Are the new truck rails wider apart that the old style? What about length? what I’m getting at, is that i

LOL, that is like asking why won't my jeans form 10 years ago fit me anymore. They changed the body, even if the box is ever so slightly different it will not work.

Some of us are handy , others not so much so. If that pair of jeans is a size 12, common sense will tell me that There’s enough material there to make a size 10.

as far as a tonneau cover, it’s the same thing. If I can build a car from scratch, I’m sure I can modify a simple tonneau cover in an afternoon and save myself $1K.

Did you not see above that several people have done it, the box dimensions are the same ??

I think we both know the answer to that. But in case not, Nope, nor will I.

 

2-3-5 posts sure, 1-2-3 pages, no thanks. I have better things to do, here is my opinion, later. :)

WTF buddy.

 

1) Calm the hell down keyboard warrior. 

2) Was not your place to say shit, I was asked if I read the other comments and that was my reply.

 

Nothing negative or rude and if you thought it was, I really don't care.

Sorry if I read your post out of context, but I’m just looking for a straight up answer. Either it fits or it doesn’t. If it doesn’t fit, I wanted to know where the fitment issue was is all .

Well, I guess the answer is they do fit, kinda!

They do fit perfectly as is, but to make it perfect the rear seal needs to be modified. The second picture shows a small gap and apiece of 3/4 X 3/4 aluminum I installed on the rear edge of the cover. Now that I know it's perfect, I will powder coat the aluminum to match the cover and install the new seal. Doing this allows the power tailgate to work properly.

Hopefully this post will answer any questions for anyone wanting to know if the older covers fit.

I've done measurements on both trucks, and both are close. What is the fitment issue? Is it because of the Multi-pro tailgate? I don't mind modifying or fabricating something to get it to fit.

Thanks for any reply.

It will fit. I have a Extang hard fold that I bought for my 2017 Chevy Silverado and we put it on a friends 2020 Silverado to see how it would fit. I just ordered my 2020 and I'm going to use it. The bottom of the box is different but the top rails are less than 1 inch different.

The top rails are not less than an inch different, they are exactly the same. As I said in my last post, the only difference is the sealing area at the tailgate.

can you detail what you did to the rear flap at the tailgate? I have the same setup. Thanks

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It really is comical when people don’t agree or see the reason some people prefer the older vehicles. They become condescending. All the while they may be busting their knuckles on old vehicles. I have found memories of swapping out engines in my old GM cars in a weekend without much hassle. Unlike today. One wrong move a computer will shut you down. Even on something as easy as a brake job. There’s a pretty comical YouTuber called the car wizard. A garage owner who puts it all in perspective. Another Vicegrip garage that’s shows just how tough the old stuff is.

      2027 GMC Sierra: Official Discussion

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.
