Geez...I would never put 9600lbs on my truck even when he is rated for it.

 

"towing capacity" is a sales argument. Nothing more. Everybody knows that.

 

Get the tools you need to get the job done safe and efficient.

And in some cases that means get a 3/4 or 1 ton truck.

 

:rolleyes:

If the truck handled it before and you are comfortable pulling it, don't let a piece of paper tell you otherwise...... just be safe.

What sort of instrumented testing proceedures do you feel j2807 lacks? Have you read through that document to see what the new ratings mean?

It'll still holds as a sales argument...

And I didn't question the "j2807".

You make no sense. J2807 is what GM now uses to rate the towing capacity of the 1500's (which chaged very little from '14). You said the ratings are meaningless. But you don't question j2807. Which is it?

I allways pulled more than the GVW if my truck could do the speed limit. The key is and allways will be is the trailer brakes. These gas trucks now days have the torque rating and twice the HP my first haul truck. My first haul truck was a 91 Dodge Cummings and I haul on a fifth wheel 33000 combination truck was rated for 12k trailer was rated for the rest. I would load my equipment over the trailer axels my 3/4 ton truck would only squat about 2 inches. Most of my stopping power was handled by the trailer brakes, that's where the load was. If there was an time the trailer brakes got weak the load would transfer to the truck and the truck would and could pick up the slack. Being older and wiser the only thing I would change is the first truck would have been a dually four tires are better than two for heavy loads.

Based upon what? Have you had issue with them while towing? I don't think I've heard of anybody having any braking issues while towing with one of these. We now know for a fact these brakes will pass the SAE J2807 braking tests with a 12,000 lb trailer without any trailerbrakes! Compared with that, a 9K trailer with trailerbrakes is cake.

 

That's a bit of a stretch. J2807 braking tests are only from 20 mph. I think every state in the country requires e-brakes over ~3000 lbs anyways. That said, rules or not, we want the trailer stopping the truck at these weights... not the other way around.

Well, I think they kept the speed fairly low just for that reason--it's a test without trailerbrakes making it excessively hard on the truck's brakes on purpose--which as you said, isn't something that should ever happen in the real world. Given that, 20 MPH is plenty speed to document the truck's ability to bring the trailer to a stop quickly. Higher speeds could mean brake fade, but they test for that by doing multiple stops back to back. With a full weight trailer not using trailerbrakes at all, that makes for a pretty grueling test.

 

The biggest problem in years past was brake fade while going down a long, steep grade. Luckily, these latest trucks' grade braking/exhaust brakes, etc, (along with much bigger brakes than older trucks) has made that largely a thing of the past.

A agree, but the energy that has to be dissipated from 40 mph in an emergency maneuver will be 4 times higher than a 20 mph stop. I can't imagine strapping 9k lbs to one of these trucks and going down steep grades, or driving along busy highways. A back road at 30 mph wouldn't be too bad, so long as there weren't many hills. Even if the truck will stop, the trailer is going to just push it around sideways. There's just not enough braking surface on the 4 truck tires to do the job. The weight on the trailer tires means that e-brakes can put that friction to the road.

 

I'm pretty sure we're in agreement here, but hoping nobody would be foolish enough to go towing those kinds of loads w/o trailer brakes.

Yeah, we're in agreement if you're saying towing 9K without trailer brakes is a no-no. I wouldn't do that.

 

But if you're saying you wouldn't tow 9K at all, even with trailer brakes (as some others have been saying), I don't agree. There's no justification for it. These trucks handle that weight just fine, even down steep grades. Years ago when tow ratings were less meaningful and 1/2 tons were much less capable it may have been true, but it's just not anymore.

Yes... that's what I'm saying. Trailer brakes needed (required) at heavier weights.

I laugh at guys driving a sacked out truck, loaded right the absolute MAX. And they're like "well it's rated for it" lol

 

Wife and kids in the truck, Rollin thru the mountains...unreal.

 

Yesterday, I passed a guy that was doin 30mph up a hill in a tundra towing a 25' camper, the camper was hooked to an 18' boat and he had a quad in the back. Just plain stupid.

I saw a guy doing the same thing the other day on I-80. Pickup towing a camping trailer with a ski boat hitched to the back of the camping trailer. The overall length was more than a semi trailer (might be mild exaggeration but you get the point). Didn't even know that was legal!

From experience.

 

Cc 5.3 with 3.08 changed tow ratings in manual by alot. I bought thinking I could tow camper but when it changed now I am too heavy.... but still tows good. For 2015 it got even lower....900 pounds less than v6. Read the "Towing with 5.3" thread. I wish GM would change my gears for free. Legal issues.

 

Btw...my camper alone is around 8600

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
