GM's Max Trailering Package

X2 to Jerem0621;s comment and add...going by marketing nomenclature is risking getting caught in the marketing “king of the hill’ positioning where things are taken out of context (true, but not the whole picture)

Suggest looking at the OEM ratings and do the simple math using their ratings numbers.

GVWR, front & rear GAWR and their listed curb weight (not the old stripper model they used to employ for these “King of the Hilll” marketing, but their true weight as shipped from the factory)

But first decide if you believe in the OEM ratings. Huge and never ending discussion on ‘which’ ratings to ignore or follow. It is a very personal risk management decision.

IMO, the most important is the rear GAWR, then GVWR, then the rest of them.

Actual weights best, but if you do not have one or the other or neither...use their listed GVWR & tongue (that will provide the basic tongue percentage to calculate vs the actual weight)

Most of the weight on any pickup will be over the rear axle. Look at any pickup from the side and notice that the rear drivers door edge is about half way between the axles. Meaning anything loaded in the bed and/or on the ball will place the majority of that weight over the rear axle.

Why as you move up in the capacity/rating scale of TV’s, the rear GAWR jumps higher. Why half ton’s have many different rear GAWR and higher class starts at 6,000 rear GAWR

Nothing wrong with any pickup class, but just understand that and forget using marketing nomenclature

Also, understand the “corporate component/systems stock room” and is where many think they can guess which parts are needed to increase their ratings. They maybe correct, but that doesn’t change the OEM ratings.

Weird...posting via my iPad has clicky’s not work...

Poke around to see which half ton you like. Plus it has a fairly good glossary of towing terms

Dont get too hooked up on the max trailering number. It has zero to do with real world capability Of a half ton.

I've got a 2015 with the max trailering package. I tow 8,200 lbs and wouldn't go any heavier with this truck. Even with a payload of 2,015 lbs, I've maxed the GVW with my setup and no water in the trailer.

I like my truck but am thinking I will have a 350/3500 next. Just waffling between the 6.6 gas and the 7.3 gas.

Also wondering what a 2015 GMC Sierra with NHT and ~45,000 kms is worth.....

If you are towing in the mountains a lot and want to stick with a half ton, Ford's 3.5 ecoboost will be hard to beat. However, GMs's 6.2 liter v8 is a great motor as well but I would rather have the turbo. For what you are asking, the right half ton will do the job but you must be sure it has enough payload.

Let me throw you a softball: WHY would you rather have the turbo over the 6.2 “pure grunt” as I’d call it? Just an honest question, I don’t think there’s a wrong answer and in no way am I knocking the 3.5L eco.

Truth be told, our 5.3 in the Av had plenty of power this summer with our current load, it was more the tranny that I was watching the temps on.

I owned a 5.3 Avy that I replaced with a 3.5 Ecoboost. Have you driven an Ecoboost?
I replaced the Avy because I bought a bigger and heavier 26ft TT, after selling my 24ft Hybrid TT. The Avy just wasn't up for the job, through our Western mtn ranges. Plus the payload capacity was only 1357lbs.
The towing difference is AMAZING! My F150 Ecoboost has 1828lbs of payload and WAY more power, especially in the mountains where it really shines.

I have driven one, just a few weeks ago actually. It had plenty of get up and go, but granted that’s completely empty without any weight behind it. But I was impressed.

Sounds like exactly the situation we’re in, except we’re ahead of the game knowing we’ll need more power before the bigger trailer. The Avalanche is a beautiful truck, but we just need more. Hence the reason I’m only looking at trucks with the max towing packages. Our Av has a higher payload than 1300lbs, it’s more towards 1800 I believe, but just not enough power for what we like to do.

I think someone made the comment above on the diesel - if we were going to be an extended period it would make sense. But we’re vacationers, so two weeks probably max a year at elevation. I’ve gotten used to slow! We were stuck behind two VW buses going up Monarch Pass in a Colorado this summer doing maybe 25. I finally got around them and tootled along at 35-45!

@jck, I didn’t know that LT 275 55 20 tires weren’t made in 2015. I picked up a set of used LT tires that size last year that had a 2016 born on date.
And now there’s dozens of them. Not awesome load ratings but 2680 lbs at 65 psi.

Another motor to think about, altho maybe above budget, is the GM with the diesel. Mid 20's city, mid 30 hwy empty. Probably like all diesels, low to mid teens towing. It would/could be better at elevation if you go above 6000' frequently due to the turbo. Under 5-6000', not sure a turbo/super charged motor that is similarly power speced makes a really BIG difference in total towing fun per say. both do the job, but with different seat of the pants performance etc.
WHere you are in Wisconsin, A forced induction vs natural aspirated may not be that big of a deal. If you head to the rockies 3-5 months of the year.....yes a turbo makes a difference. One trip every 3-5 years, get the cheaper motor that does the job where you are, go a bit slower at elevation.

An advantage to a forced induction motor like the Ford eco boost, a majority of dusel motors, is the fo not lose HP at higher elevations like a natural aspirated motor like the GM V8,s, Ford's 305 etal. They lose 2-3% ofHP per 1000' above sea level you go. So at 10,000' like you are at highest points in Yellowstone as an example, that 6.2 is down some 30% hp, the turbo version is still cooking along at potential max HP.
I took the same trailer, etc thru Yellowstone with a 454, 9 years latersame trailer, older teens about 1500 total lbs heavier with a GM 6.5 turbo with 50 less HP, it smoked the 454 going up the same 15% grades at 9-10,000' that the 454 could not do but in 1st gear ofits 3 so auto. The diesel with 5 gears, di it in third, or equal of 2nd with the auto. 10-15 mph faster.
Having a turbo at elevation helps.

That’s perfect, thanks! I think I’ve heard that before, but that helped clarify it well.

Had a 2015 Max tow GMC 1500 If memory serves me wright it had 4300 lb. rear axle and around 1800 payload . I think the standard rear axle is 3850 lbs. I had a 28 foot Keystone bullet that was right around 6500 lbs. Truck handled it fine but you could never drive with one hand . Trailer didn’t sway but truck was constantly moving around probably because it had 20 inch P rated tires . I don’t get it you buy max tow / max payload and they give you P rated tires shame on GM . Kept it two years and got a 2017 GMC 2500 HD problem solved

That’s a nice excuse to convince the wifey you need a Duramax Denali, but you and I both know that the tire store coulda fixed that problem for less than $1000. Or you could just air them XLs up to 50+ psi in the rear and solved most of your “issue” for free!

The tires that came on my 2015 NHT max payload with 6.2 and a eight speed were those wide 20 inch tires P series I had them aired up to the max to no advail . At that time you couldn’t buy a LT tire in that size. So it would have required a rim change also.
We’re not your local traveler we’re you can get buy with what you have.
Two trips out west first to Oregon 7200 miles
Another to Black Hills , Devils Tower ect 4500 plus miles . There’s a reason you don’t see half tons out West . The wind is always blowing hard and the grades are long and steep. Buy the correct product for the the Job and enjoy the ride

I drank the Pink coolaid once and will never buy a 1500 again
1989 Ford Diesel
2002 HD 2500 8 liter 498 Cubic inches Allison 5 speed trans
2004 HD 2500 Duramax
2015 GMC 1500 6.2 eight speed
2017 GMC 2500 Duramax five speed
2019. GMC 2500. Duramax six speed Best truck of all of them

People that say 1/2 tons and 3/4 tons are the same price have to stop comparing msrp and actually try to get 10K off a comparable 3/4 ton. They'll kick you out of the dealership! Remember, I said comparable, not a Denali or Platinum diesel.
