2021 Sierra 1500 3.0L towing without the max trailering package

Hello everyone! I just recently purchased a 2021 Sierra 1500 3.0L which will mainly be used to tow my center console around to local lakes and to Florida a couple times a year. I did NOT get the max trailering package mainly due to a mix up and having to switch trucks because someone purchased the one I went to look at and I didn't notice (yeah). 

 

My boat is a 24' center console and weights about 2500lbs, plus around 800lbs for the engine, around 800lbs for fuel (105gal tank) and the trailer. My best guess is between 4,500-5,500lbs. When towing to Florida the rear end sagged quit a bit. I picked up some Airlift 5000 air bags and compressor hoping this will resolve the sagging but now I am wondering if it will help at all. We used to tow with a 2018 Tahoe that had the max trailering package so it had air bags on it already. To be completely honest, I do not know exactly what the 9.76" rear axle and 3.42 axle ratio in the max trailering package will help which is what comes in the max trailering package. I know it has heavy-duty rear springs as well which I figure would of helped with this sagging.

 

Will I be creating problems with the air bags? Obviously I don't really want to trade in the truck already for a new one due to the lost money on having to pay taxes twice, not to mention the loss in value from having 2,000 miles on it already.

Given that max tow weight is gross weight, your actual tow weight will be less. By the looks of the photo, the tongue weight may be to high. Doesn't look like the suspension is set up for the load.

Get a set of Roadmaster Active Suspension.  I added the HD version to my 2020 3.0L Duramax, and it's great.  

 

I was towing more weight than thay recently with two different travel trailers.  

 

You are under the max tow rating certainly so no worries there.  Of course as you add weight to the rear the suspension will compress, it will not remain level.

 

You could try a weight distribution hitch if needed.

I haven't seen that before. So it looks like it is preventing the leaf springs from compressing as much with that Roadmaster Active Suspension. However, I did already purchase the Airlift 5000 Air Bags and compression before this post. It kind of does the same thing it appears by offloading weight from the leaf springs to the axle I guess.

Yeah it definitely brought the rear down. I've already purchased this with the compressor and hoping it will work: https://www.airliftcompany.com/products/air-springs/loadlifter-5000/ I figured the bags were cheaper than trading it in.

You can't get NHT max trailer on the 3.0 diesel in the first place.  Only on the 5.3 and 6.2.

 

Looks like you have too much tongue weight.  Might want to weigh the tongue to see what its at.

Not an expert on trailers, but looks like the boat trailer may be poorly designed, even downright "fishy".  With the tandem axles located completely "aft" much of the weight of the boat and outboard is probably being directed on the tongue of the trailer so as Phantom and newdude have suggested get that tongue weight. That trailer looks more suitable for a boat with 3 large offshore outboards hanging off of it.

Definitely hit the scales.  Even if it was 15% you're only looking at a tongue of 825 based on your 5500 lb estimate.  IMO Bags in this case are the way to go to completely level up.

I recently towed more weight than that with my 2019 GMC Canyon and measured the tongue weight at just 9ver 700# (max on the Canyon is 770).  Before hooking up the weight distribution bars, squat at the rear of then truck was a hair over 2 inches.  The truck in the picture looks to be squating way more than that, leading me to think the tongue weight is way too high.

 

Personal opinion: things like air bags seem like bandaids to me.

+1000 on the trailer tongue weight. I tow my boat that weighs ~4K and the sag is minimal. I haven't measured it yet but just eyeballing it looks good.

 

Your trailer wasn't built properly for your boat. I'll attach the latest picture of my boat/trailer attached to my truck. I doesn't show the truck but you'll see what a properly built trailer looks like.

You could be right...but the grass lot he's on doesn't make it slam dunk that he's overloaded to me....just over 2 inches of sag is about right.  It'll be interesting what the scale ticket shows.

Very true. The picture could be exaggerating the condition. A tape measure will prove helpful.

The picture was taken with a widescreen shot which could be. It was sagging but the chains still were not touching the ground with the stock configuration. I'll have to hook it back up and measure the distance for y'all. I'm thinking bags will resolve it but as far as the trailer goes, these are all the same kind of trailers I see with these kinds of boats. The axles are in the rear because I assume the majority of the weight is in the rear.

I'll have to see where I can get it weighed because that would be a good thing to know. The specs show dry weight at 2,750lbs, plus the F250 XCA outboard should weight 558lb (plus the rigging), and fuel at 6lbs per gallon would put about 600lbs. That still is on under 4000lbs.

Below is the only other picture I had before I went on the trip. I'll have to get new ones

I had a 2014 z71 and I installed the Firestone air bags, they work great. I tow a car hauler every once in awhile and it felt like it was too much for the 2014 z71 to handle. I added the air bags with just a manual valve stem and the truck towed like a dream.
 

I just picked up a 2021 3.0 RST and will be adding the airbags to this truck as well.

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

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
