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

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.

      Oil Consumption

      By diyer2 · Posted

      I have changed oil and filter for years by starting a cold engine to warm oil up, let it run 5-10 minutes depending on temperature. Drain until it starts dripping, refill with quantity from owners manual or get it close.

      Fluid Change Questions

      By Chuck FB · Posted

      I changed the factory fill oil in the rear diff of my truck for the first time today and the miles is close to 9000 on the truck. There was a lot of fines on the magnet, a very thick layer but working it through my fingers it all felt like mush and as most know it appears like graphite, so no surprise chunks anyway. Certainly was time to do it from my thinking and could have been done sooner but the oil didn't look awful but sure wasn't new looking and never expected it to either. I did use some solvent to help me clean out the bottom area of the axle housing, just get any other stuff settled at the bottom washed and wiped out of the housing for the bit of effort it takes. I used Amsoil Severe Gear 75W90 in the easy packs to try out what they are like and I used up 4 packs and didn't spill much at all in the process but did take all four of the packs and go to the work bench and emptied them into a measuring container and there certainly was some in them that added up to something, then poured that into one of the easy packs and squirted in what I could get out of it. I would say the level is within 1/8th of an inch of being level with the threads at the fill plug so just the perfect amount. Once again, more than what GM says the fill volume is but computes with what others are adding to their rear diffs as well.
