I see what you did here and i like it my question is there a way to put the bar behind the bumper instead of infront if that makes sense?

This is the best thank you!! And lets be honest they arent smart lol

Do you have a bulletin on that?

Well for those of you who recognize my name you know my 2020 trailboss was a lemon due to exhaust and transmission issues. Got a nice pay out after I traded it in for a brand new 2021 sierra 1500. Well here we are with more issues (FML life). Trucks a 6 month old bought in June new 2021 Sierra 1500 3.0 duramax. So about a month into owning the truck (middle of summer) i went to start the truck, foot on brake, push the button and to my bewildement the truck just sat there cranking trying to turn over. Couldn't get it to stop either till it seemed like its 30 second cycle stopped. Thought that was weird. Fast forward to now. It has happened probably 5 or 6 times in the last 6 months in various times. But in the last 2 or 3 weeks its happened twice. So its getting more frequent. I was able to capture a video this time Im going to take it in for a checkup after Christmas but we all know theyll just say "there is no codes its working as desired". But i know i need to start the paper trail. I also about 2 weeks into owning the truck had smoke billowing out of the oil cap. I did get that checked out and they said it was fine and "normal" i need to look myself again though before i take it in and if its still happening ill have them service that too. Has anyone had either of these issues? Im beginning to think im a bit cursed. VideoMeme08230520122021.mp4

I bought mine new in june.... crew elevation 4x4. I have never towed with it. I don't hot rod it and i rarely leave it idle too. I do however have 6" lift and 35s... but i can't inagine thatd cause me to use almost double of you...

I have 12k miles on mine. I have added 10 gallons total to mine maybe 12.5 can't remember.. i do 90% highway. 1500 miles ago i filled it up pretty much full and its saying i only have 150 miles left... this seems like way too much?? I filled it up day one full that lasted me close to 5k-6k miles. Ever since then i feel every 2000-2500 miles it needs filled up. Im about to fill up the tank full at 12k miles and will monitor how many miles it lasts.

Im a little afraid of that. Might have to settle for cold air intake for now

Been patiently waiting for anyone to release a tuner but am yet to see any updates. Last i heard was fall 2021 for banks but nothing since https://official.bankspower.com/insider_news/3-0-liter-duramax-derringer-development/

Ive ran falken Wildpeak at3w for the last 4 years on every vehicle. For the price, ride quality, thread lift and quietness of them you really cant go wrong. They arent as aggressive looking as the ridges but still look nice to me

How exactly did you install this?

I can be of some assistance here... I ran a 4" lift with 35s in my 2020 silverado. This 2021 sierra is 35s with 6... So a 35" WILL fit under in the stock locations. On my silverado i used my stock rim with a 35 and it fit perfectly. No issues. This sierra i cant use anything under 20" due to the lift kit. So i got a match (off brand and super cheap) size and offset wheel with matching (used) 35" tire for my spare. For me spares basically to help get home on vaca and everything. I havent had a chance to see if the tire fits because on my 2015 when i ran a matching rim/ tire the bore of the rim was too wide for the stock spare tire lift mechanism to grip the rim and lift it. Needed to be like 1" wider. So i just left it in the bed. I also run a full size floor jack. I keep the handle under the back seat and then the jack in the very very front of the bed secured with a ratchet strap. I also keep a plastic tote of tools and other necessity incase im ever stranded. Been running this setup for years now. Only thing i dont like is the spare in the bed cause it takes a lot of room up. But everything's also under a tonneau cover

I was afraid of that exhaust wise

I am thoroughly impressed with this truck. Its great. Looking forward to the first time i get to tow with it. Ive heard about the derringer. Wonder when we will finally see it tho

Cold air intake and exhaust (especially exhaust) should not void anything

I upgraded from a 5.3l to a 3.0 duramax and for my first diesel truck im absolutely in love with it. I love the sound of it. I have a 4.3l v6 2015 before my 2020... put a cold air intake on it and it really did open it up and made a huge difference sound wise. I want to increase the exhaust sound and make the truck louder. I cant delete it yet and dont think any programmers do yet anyways... but has anyone done an exhaust or cold air intake? Did it make a difference?

Did it do anything for sound or mpg?

Hmmm. Interesting. Side note... how you like the CAI?

UPDATE Took it to a dealer with good reviews. One of the most ghetto/ ratchet dealers ive ever seen... mofos automatic door shut on my hitch. Thankfully didnt mess up my truck when i pulled in... Anyways they had it for like 5 minutes and said its normal... thst the diesels do that. They compared it to a like truck apparently... but the only diesel is used and sales guy wasnt there yet so i couldn't see for myself... but assured me it was normal.. So help me out here... whenever you guys drive your truck today. Take two seconds before shutting it off and see if yours smokes like mine. Cause im not convinced...

Other weird note... drive same way to work at 65 mph... my mpg went from 28-29 to 21mpg

Just checked oil cold. Its sitting at the very top of the max fill hash. Looks black but not watery. Coolant looks good. The clear bottle is about half way full

Im very capable unfortunately just no time to look at it. The cap had oil on it and the little indented plastic part the cap sits in had oil around it. Didnt check coolant. But before work i will check the coolant level and the cold engine oil level. Dropping it off in the AM.

Looked good. Pretty black but my friend said thats normal for diesel oil? Wasn't milky or extra liquidity

Oil level (checked it when it was hot) was at the top of the hatch marks. I started it a little bit ago cold and it did it again. Videos from when it was fully warmer up (not over heated per dash tho)

Make me wanna puke. I am still selling my lemon lawsuit from my trailboss i traded in for this. Also was able to get a video posted. Check it out let me know what you think.
