GMC Sierra 6.2 V8 towing 8000lbs

[@SF-fm7ov]

I keep coming back to this video. I find it amazing how easy it is to hear your softspoken voice, even when your wife is holding the camera. GM has done a wonderful job with their noise cancelling technology. As an older guy with bad hearing, I hate competing noises. If I wasn't towing at 11,000 feet, I would absolutely buy this package. You may have convinced me to buy it anyway. "My mind is blown".

[@panchovia]

Weirdo

[@kingaarons]

I have a very similar setup... 2015 gmc 1500 6.2 SLT, so 1900 lbs payload. I tow a 7200 (dry) fifth wheel, when loaded likely around 8500. Hitch weight was 1280 lbs when dry, maybe 1350 when loaded up. Truck handles amazingly well. I had pads nearing their end, and had to bring the brake controller up to 6.5. After I got new pads, I dropped it to 5 and may drop it down even more. Makes a huge difference... Good setup!

[@amped79]

Yes it has towed my trailer with ease! I'm happy with it.

I just purchased a ‘15 Silverado 1500LTZ crew 4x4 and made sure to find one with the max tow pkg (8L90 / 3.42) and the 6.2L. I got her to pull my 23’, 6500# camp trailer. In SE Idaho we’ve got so many grades to our camp areas that I wanted a 1/2 T that could pull at 65-70 MPH without having to rap out the engine. I’ve got a cold air intake on the way and am ordering a DiabloSport Predator 2 tuner that will disable the AFM, tighten the tranny shifting and combined with CAI, should add 30+ HP & TQ to her in tow mode. Next will be to open the exhaust (muffler replace and resonator delete)- the 6.2L begs to be heard. Real world tests are the best and your vid popped on my feed. Happy trailering!

Nice 6.2L I drove same 2018 SLT with the 22" wheels not max tow and WOW was it super quiet. More so than an identical 5.3L which was nice and quiet too.

I believe all trucks with the 6.2L have active noise cancellation which makes the cabin extremely quiet.

Thanks for sharing that video. I noticed your Sierra had no sag for towing a 8,000lb travel trailer. Did you install airbags or is that ball thanks to the weight distribution hitch? I’m curious to know, since I have a similar truck and looking to purchase a travel trailer soon. Thanks. 👍🏼

[@amped79]

Nothing is modified on the truck but it does have the max trailering pkg (not to be confused with tow pkg) this gives it stiffer rear leaf springs & shock absorbers among many other things to improve towing/hauling. I do use a WDH still as my trailer tounge weight is about 900lbs

Nice, I'm pulling an 8,000 lb 32' trailer with my 1500, but I only have the 5.3.

Nice set -up indeed. I towed through the Rockies a Nash 24M (7000GVWR) behind a 2016 Suburban equipped with the max tow package and the 5.3 V8. Wow, in this configuration that engine was a real dog. Specially up where the air gets thin. I wished that I had the 6.2 for that trip, but the marketing folks at GM chose not to make that available to us Chevy buyers. They came to their senses and made the 6.2 available in the suburban for 2019. I wish that they would offer a turbo charged gasser, but I guess it would slow Duramax sales. Too bad. That said, we like our Nash, no problems to speak of in 3 years of use. Enjoy your rig and safe travels.

Bought a 2017 August 2019 optioned the same as your truck. Based my purchase on your video. I knew that I should wait for one to show up for sale and one eventually did. I am so happy that I waited. Better performance than I expected. Worked fabulous on tow to Arizona 6000lb TT. The only thing now is a bit of hard upshift and downshift at low speeds, 1 to 2 and 2 to 1 (parking lots) maybe a slight chatter or vibration as another guy reported. Maybe GM dealer here has a fix which it will go in soon. Have heard lots of this happening. Your truck do that?? Other than that love it. Great video.

[@tannergregg7828]

Thanks for the video...it was a major factor in my search for a used truck. I really didn't want a 3/4 ton since this would be our second commuter vehicle as well. I finally found a 2017 GMC Sierra SLT with the max trailering package and I jumped on it! I have a 7,000 pound 33' trailer to pull and this checks all my boxes with a lot of head room left over! I'm curious if you are using the stock P rated tires that came with the truck? I went with LT 8 ply tires after experiencing massive sway with my old 2003 Suburban with P rated tires. Bumping those up to LT tires was the single most important thing I did to improve stability.

[@amped79]

I actually do have p rated tires but I air the rear to max psi and front to 40psi and it seems to be working out completely fine. The LT choice will be something I will have to consider on my next set of tires as they will inact a noticeable fuel milage hit for all the time I'm not towing. I am still very happy with my setup and u will love that 6.2 power train. Thx for the comment

Hi amped! Great GMC geek out video! I have 2017 Sierra 4x4 6.2 max trailering 20 inch rims 15,000 miles. Quick question: Have you had a torque converter chatter issue after a long distance tow? Towed 4,500 pounds from NE USA down to the Smokys and back. Got home and 2 weeks later had the chatter on a steady upgrade (1 degree) at 40 mph keeping steady on the throttle, no trailer. It would also float/ hunt for lock up on the highway. TSB for upgraded trans fluid was done at dealer under warranty and no issue since. Wondering if you had/heard of issue? Also, for the mpg info guys are looking for: 95 degree Fahrenheit days, ac blasting, trailering on Interstate 81 and 12 percent grades on Interstate 26 is good for 14 to 17 depending on the weight of your foot and your hills. Unloaded highway 20-25 mpg with a best of 26. Unloaded city is 16-18. Ac on take off 2 mpg. When the temp goes below freezing, take off 3 mpg until you are 45 minutes or better into driving, then it goes back up to what I just stated. Thanks for the video!

[@amped79]

Hey great info! I have not had any issues with the transmission or torque converter yet but I have heard of people having issues specifically with the 14-16 trucks. Longest tow I have done is 3hrs but I have done it probably 8 times since buying the truck.

[@mmcintire66]

I just bought a 2016 with max tow. 6.2 and 8 speed. There was an issue with the transmission fluid causing a shutter (feels like a rumble strip) and posted a bulletin that they released a new fluid to put in these trucks to solve the problem. If your under warranty a dealer will flush it and replace fluid for free !

[@nicholasierubino8223]

@@mmcintire66 wasup? Yeah I found the TSB after I saw this video. Turns out it is part of a possible class action between GM, Castrol and ANYONE with an 8l90! Went in for the fluid change, all was well for a while. Then the trans started to do some funky hunting stuff, took it back they said it was the fluid temp sensor. When the truck took off on me a few days later (thank god I was in my driveway and alert). Couldnt get back to dealer and after that air ball and everything else i had in for warranty took it to the local shop. Turns out they didn't perform ANOTHER tsb for not only changing the fluid but also to clean/reset throttle and doing a flash on the TCM. Flash done, throttle cleaned, picked up 3mpg 👍. Submitted a claim to GM for the botched stuff, only got $202.39 for a $1019 out of pocket repair that the shop charged EXACTLY what the dealer would if it wasn't under warranty (they were sooo cool). All was well for a while, then the shudder again 🤦‍♂️. Took it back to the dealer and politely shoved it in their face. They admitted the second time they had the pan down, they installed the OLD DEX HP not the new Lv Mobil ATF1 (oi). So, flushed again for free. Now we wait. The tsb states that if it happens a second time, NEW TRANS. But the dealer isn't letting that warranty claim through. Sorry for the rant. But there is some valuable info for all in here. Still live the truck and dont want to get rid of it.

Tell us about any transmission trouble you might have had. Is the 8L90 transmission functioning like it should. Have you encountered the torque converter shudder ? Lots and lots of complaints are coming in on the internet. Myself included. My 2018 has 20,000 miles on it. At 18,000 miles the torque converter began to shudder, so I had the dealer flush the fluid out and replace with the better fluid as per the service bulletin that is out. Shudder is gone now but it still frequently hesitates on acceleration and sometimes slips. I'm not happy with GM and I've been a GM guy for 40 years

At 3% loss for every 1,000 feet of elevation, I believe I am under 200 hp from the 285 stated hp. My truck pulls well up the canyons and on the Interstate and other roads. I am torn between going to a 2500 Duramax, 6.0 or trying the 6.2 half ton. Any thoughts?

[@elonmust7470]

I have the same dilemma. 6.2 rst, or duramax hd.

[@adrianlaverick8040]

If the half ton is rated to tow the weight you plan on towing, and you don't plan on towing all the time you are in the truck, get the half ton

[@brandedmcgowan9414]

Normally the lwb trucks has a lot of sag but this one took weight in the bed and trailer well and squatting about only 2 inches. Newer GM trucks (like the older Fords till 2014) levels well with weight behind it better than the older gmt400 and some gmt800 trucks plus the current gen Fords.

[@dtaylor5493]

I have the EXACT truck. Colors and all. We tow a 28' Triple E 5th wheel. I had 10 ply tires put on, Firestone airbags, and a 16k LB dual pivot hitch. Lockout 6th gear, tow haul, and we cruise at highway speed and average 11mpg. Weight wise, the trailer is about 1100lb on the hitch, which puts us about 600lb over weight on the truck; then again, a bag of softener salt will overload a half ton :)

@Grumpy cat I'm checking it out. Thx.

[@SF-fm7ov]

I am a huge fan of using WD Hitch. I tow an 8,000-pound TT with my 5.3, Shifting weight from the rear to the front axle improves safety, steering, and handling. I have also towed on windy highways thru Wyoming. A WD Hitch with a sway bar makes it a more comfortable drive, especially when a semi goes by. Of course, the heavier the trailer, the more important it becomes. Many people use air bags to level the load but those do nothing to correct the uneven load. Weight distribution does. Some vehicles state that a WD Hitch is mandatory over 5,000 lbs.

[@alexzaldivar5004]

I have the 2018 1500 Denali 6.2l and im gonna pick up my brand new camper in a week that weighs 5795lbs hitch wt. 600lbs 11ft tall. 31ft long. You ever have issues of it being a small truck with a longer travel trailer thats sits high, and does the trailer ever move your truck around? Ps. I am getting a weight distributing hitch put on when i get the trailer which im guessing will help the ride be alot better.

[@amped79]

My truck has the max trailering pkg so it has the higher towing rating then the denali. (gearing 3.42, stiffer spings/shocks and transmission cooler upgrade along with the tow mirrors) It has absolutely no issues towing around my 30ft 8000lb trailer which is 13ft high so it is a tall trailer. I use a weight distribution hitch. I would say that your trailer with the weight you mentioned will tow completely fine with your denali and you will be very happy. if you have the 5ft box you will suffer some stability over the standard 6.5ft bed as wheelbase is shorter.

[@justinmiller33]

Hi rich r, the max trailering pkg with 6.2 comes with the 8speed 3.42 gears. The max trailering is the only way to get this gear ratio. If it had the 6speed a 3.73 was available with max trailering but without the 6.2. Highest Trans temp i have seen is 192F.

[@jaybilawchuk2225]

[@johnculver8707]

What setting do you use on your brake controller? Thanks

[@amped79]

4.5 but this is something that is completely based off of the trucks brake controller and the braking system on your trailer. I may make a video on setting up your brake controller. Essentially when putting on the brakes you should feel an equal feeling of braking between the trailers braking force and your trucks. If you have too much gain, you will be locking up your trailer brakes. Too little gain and your stopping distance isnt good because your trucks brakes are doing too much of the work and the trailer brakes arent doing much.

No problems at all even though i have heard of some people having issues with hard shifting. In the first 5000km i noticed hard shifts from 1-2nd gear mainly in parking lots when going very slow. I think that this transmission learns your driving style and thus very seldom do i experience a hard 1-2nd shift or banging of gears. Its road manners are excellent as it does not hunt gears at all.

Instead of D on the shift column select M or L depending on year of your truck. Then you can use the + or - on the column to signify the highest gear u want the truck to operate in. Very useful for gearing down on steep grades as well.

[@little78d]

But you loose your auto grade braking when you shift out of drive into manual mode.

@@little78d And?

[@probuiltshop]

What brand hitch setup are you running?

[@amped79]

It's a EAZ-lift WDH pretty cheap and was given to me. Does the job and haven't had a need to upgrade.

[@williammejia598]

What is the gcwr of that truck?

[@RedHagar]

My 2017 is identical and is rated for 17,700 lbs

[@nathann9889]

Random question is there a gmc sierra 2500 6.2l

[@amped79]

It is a 6.0l in the 2500hd or 3500hd

[@jdmanny450]

What's the weight difference? Between the 3 truck ??

[@Icutmetal]

jdmanny450 Huh?

[@TC-tw5zk]

What WD hitch are you using?

[@amped79]

Hi Tom, it is quite old and i am unsure of the brand. It is a very basic trunnion bar style and has no additional sway control. I may one day upgrade to a nicer WDH.

[@CR500R]

What was your rational going to a 1/2 ton truck from a 3/4 ton truck?

[@tylerkellytylerkelly]

No 6.2 in the hds

[@matttheplumber00ify]

8000 lbs?? How is that? Dry weight says 5700lbs

[@i39440]

GVWR is 8,000 lbs. Once you load it down, that dry weight goes up quick.

[@kevinswartz2396]

Not that much

[@allen2959]

If he has his water tanks full it goes up quick.

[@matttheplumber00ify]

Unless you carry 270 gallons of fresh water!

[@tumbleweedking5668]

Not anywhere close to 8K but still tows well. 5600 lb trailer empty.

[@Icutmetal]

Ok 👌

[@Bangabalunga]

With such a beautiful truck and house, why did you buy that junk glued and stapled travel trailer? I would have expected you to buy an Airstream.

[@giobikefans]

Nash is a sweet trailer!

[@heritagevalleypropaintingl7911]

@@giobikefans 1000 percent nice trailer or the money. That is the dumbest comment i have heard. one buys a nice truck and house and "doesnt spend the money" on a trailer to match the rest. Whats the problem with this world. Geez. You dont spend all your time in your trailer so why does one make a comment like that. His priorites are his not yours . Matin you need to puff your chest in the campground with the nicest and best .

[@normandbrunet9284]
