Enough

My 2020 was "fixed". It still leaks. I can push the headliner up and see no cracks in the plastic molded to the slider. The water actually runs all of the way to the driver's side of the plastic then runs down the inside of the glass. So far the headliner is dry. I have to believe the back of the spoiler or the 3rd brake light are the source of the leak. I just wish there was a way to take the headliner completely out without damaging it so I could locate and fix the leak.

I've seen a guy rolling around in my county in a custom T-1 regular cab short bed. Traffic jammed me up and he got away before I could catch up to him.....lowered 6-7 inches on some massive tires and wheels but not laying frame. It's got a great stance ! He appeared from behind other vehicles quietly and disappeared just about the time I realized what it was. Probably totally useless as a truck but the ear to ear grin on his face spoke volumes ! I think I actually drooled a little as he went by ......

5.3. Running 87 octane I'm averaging just a tick under 24 MPG on my 58 mile round trip commute and have more than enough power to tow my boat. When the roads are wet and the bed is empty I have to be careful of the back end wanting to come around if I push too hard on the skinny pedal. I don't need any more power than the 5.3 gives me. Even the crappy gas served up in neighboring Florida doesn't give me any problems. It always seems to be a couple of points under the posted number on the pumps.

My understanding from other posts on this forum is that even if you got "lucky" and don't have DFM your engine still has the same internal components that mine with DFM has. You just don't have the chip to activate them and should have gotten a whopping $50.00 discount off of MSRP. The jury is still out about your chances of your truck having the same lifter failure my truck might have. 26,733 miles and counting on mine......

Two months, no codes, including on my March OnStar Diagnostics Report received Thursday 3/3/22. I back 300 feet down my driveway every night so they have had every chance to throw codes and have not. Lasfit T10 license plate light bulbs. Lasfit 912 back up bulbs. Both listed as Canbus error free on the website.

I used Lasfit LED's in both of those locations. They can be ordered directly from Lasfit or bought on E-bay. They are bright enough that I took the aftermarket LED lights that I had mounted under the bumper off and still have plenty of light to back up in complete darkness. The truck looks better without the aftermarket lights under the bumper too !

There are posts on this forum about "clunking" noises coming from the rear end as a result of U-bolts not being tightened adequately from the factory. If they are loose enough to allow a "clunk", they are loose enough to shift with a side load. Have the dealer do a 4 wheel alignment and tighten the U-bolts to spec.

After installing the Lasfit backup light bulbs my tag lights looked so yellow in comparison that I installed Lasfit back up light bulbs too. The combination is bright enough that I removed the under bumper LED lights I had installed and have plenty of light to back up in the dark safely.

I have an open invitation to all of my friends. Take me with you to go pick up your new vehicle. After I show you everything wrong with it, I bet you will think twice about buying it. I have been kicked off of a few car lots and asked not to return. Grumpy you better be careful about when and where you show that Man Card. In this world of natty light seltzer drinking. skinny pants wearing, white sole dress shoes, and commercials showing teen age boys that don't even know what a lug wrench is you might get sent off for sensitivity training and come back neutered.

If I had the space you seem to have and it were my grandfather's it would be a tough decision. Do you have time or desire to see it back together ? Remember that it will have 1952 brakes, steering , and power unless you dive down the other rabbit hole of upgrading during the build. Do you keep it original and accept the mechanical limitations of that era or build it better, safer, and more likely to be driven with modern components ? You could spend the next year or so researching online about upgrades ! At 62 years old I am trying to convince myself I have one more build in me after 8 frame up restorations over the years. But then I plop my butt in the 2020 355 HP crew cab pickup with power everything and forget about it for a while....

Well... mine is leaking from the same spot that was "fixed" the first time so it will be headed back for the second try soon. Whatever sealer they used seems to be making water track to the opposite side where it is now leaking there too. Living in a place that gets 68 inches of rain a year plus the occasional tropical storm or worse having a watertight vehicle is fairly important. Given the price we pay for these trucks we deserve better. Giving up and putting in a fixed glass only enables GM to continue passing off flawed designs instead of making things the right way. I'm too old to put up with crappy engineering. Strike 2 on this truck.

Bonding plastic and glass together is really never a good idea simply because of the different expansion and contraction rates of the two materials, but that's what we have with the sliders. Sooner or later either the plastic will crack or the glass will shatter. The urethane sealants in use now are really quite good at what they do, but the foundation they rely on is questionable. Then for good measure move the third brake light which used to mount in the rear of the metal cab to a plastic spoiler bolted to a metal roof that has holes drilled through it to mount said spoiler. They probably should have designed a sump in the rear floor pan and included a bilge pump with a float switch to the T1's. I am on my first reseal. My dealership removed the spoiler and resealed it too. I have my fingers crossed !

I had a friend in high school that thought he got one over on his Dad when his Dad agreed to let him put duals and glass packs on the family car. Friend was bad about trying to sneak out or come home after curfew. No sneaking out after the exhaust hack. One night after he had been out on an early date he tried to "sneak" back home late by shutting off the engine uphill of the house and coasting down the driveway. The over rich condition caused by the duals dumped gas in the exhaust so when he shut the engine off it backfired and blew up one of the cherry bombs. Woke the whole neighborhood. His Dad laughed hard every time he told that story. When my friend bought his own car it was so quiet a Singer sewing machine made more noise. Lesson learned.

12/19 Silao Mexico Build. Crew Cab Silverado LT with power slider. Just got finished washing the truck. Add me to the leaker club, Dammit ! E9 stamp on the glass.

Now at close to 20,000 miles on the 2020 a few more tidbits. 8 speed trans still doing great. I am amazed at the small rpm range this engine is designed to run in for fuel efficiency. Under normal acceleration I don't feel the shifts at all and even under hard acceleration the shifts are smooth. If I remember to turn the auto stop off right after starting the truck it will idle fairly smoothly in that run cycle. If I forget and let the auto stop activate the truck will not idle smoothly during that run cycle even after turning the auto stop off. Say what you want about the 8 speed's extra gearing making up for the 3.23 rear over the 6 speed with a 3.42 rear. My butt and the pull off of the line tell me different. I wish the 2020 had a 3.42 rear. Still can't get the driver's seat "just right" on the 2020. The 2018 dialed in easily even after my wife drove it and changed all of my settings and was to most comfortable seat my butt has ever enjoyed in a truck. I can't stand the electric parking brake. Unless I follow a specific procedure when releasing it and getting the truck moving from a stop there is a large jolt like the truck has been rear ended when I put the truck in drive. Start the truck. Foot on the brake. Release the parking brake. Shifter to reverse for a bit. Shifter to neutral for a bit. Then to drive. Otherwise I get hammered ! Does not matter level or inclined surfaces. Jury is still out on the electric assist steering. Sometimes it feels quirky. Missing the full center console I swapped in to the 2018 with Phil Gamboa's herness. If you can find a console for a 2020 they want close to 2 grand for it after shipping so that will have to wait. I had less than $600. 00 in the 2018 swap including the harness. I like the power fold, turn signals, and paddle lamps on the 2018 and those options are not available to swap in on the 2020. I've run 24 MPG over 400 miles average in the 2020 for weeks at a time and hit a couple of 25 MPG weeks in a row under the right conditions. 38 PSI in the tires yielded that but firm up the ride a bit. 34 PSI drops 1.5 -2 MPG. For a 4 door brick with an open bed that's not too shabby either way. The 2018 was within 1 MPG of the 2020, even with me enjoying the 3.42 rear from time to time. I like my 2020, but in a perfect world if I could go back to my 2018 without electrical issues I would trade back for it in a heartbeat.
