Sure thing.

 

Truck is a 2019 1500 AT4.  Payload capacity of 1522 (on sticker), tow rating of 9400 (because it's an AT4).
 

On the scales with my family and loaded for camping we come in at 3400lbs on the front axle, and 2900lbs on the rear axle. 

 

The trailer is a 28ft model, dual slide.  32ft tip to tip.  I run a blueox sway pro hitch with 1000lb spring bars.  GVWR is 7500, and UVW is supposedly around 6500 (I think..). We've made some extensive renovations to it, so I don't think the published numbers are accurate anymore.

 

All hooked up our weights come in as the following with the WDH engaged:

 

3250 front axle

3600 rear axle

6800 trailer axles

 

This is probably the largest I would go.  We tow across the rocky mountains on a regular basis, we get about 11mpg averaged out over the summer (10k miles-ish).  I keep the bed empty, the trailer definitely didn't have enough tongue weight on it originally, and I have to leave a couple flats of water under the front bed to keep it where I'm happy with it.

This is very reassuring of my Solaire pick. How did the crosswinds feel?

 It's usually ok, although going from my 26 model to the 28 model might have well been doubling up in terms of crosswind difference.  It's a massive change adding those 3-4 ft.  Also, at 10% tongue weight, it was almost untowable in windy situations, I would have to slow down to 35 or so, pushing it back up to almost 15% resolved it.  I'm not a speed demon though, usually keep around 65-70.

I have a 2019 Sierra 1500, Bilstein 5100's and airbags in the rear. Towing about 6500lb-7300lb (sometimes with water tanks full which is horrible to do but needed sometimes) 26' Jayco. The airbags made a night and day difference, i even didnt use the weight distribution hitch a couple of shorter runs set about 35psi. I would not go any larger than 26' with a 1500. Wind definitely wiggles you around a bit. If youre towing long distances id stick around 20'. I only tow to my private property and drop it about 60 miles each way twice a year, and to a couple state parks twice a year.

 

I also tow a 19' equipment trailer with a john deere 3025, that tows great. Ive been itching to upgrade to a 2500, but ill just push the 1500 now until I have a problem as its almost paid off.

Rule of thumb for me for comfortable towing is half the door rating. 
 

‘Comfortable’ to me is stay with traffic, have some ability to pass. Whenever I’ve towed near limit it’s just not comfortable and feels like truck won’t hold up for continued duty with those Max loads. I read this and immediately thought 2500 or up, heavier suspension and running gear and transmissions etc, heavy towing and half tons don’t really go together. Not interested in being under speed limits or struggling so my comfort levels aren’t same as everyone’s, I stay loaded fully time and we go as many weekends as we can and live in it as we go. Even with towing the half rating I still have air bags to level properly for comfortable towing as my trailer is nose heavy and I carry weight in my box, 400 lb fuel tank just part of it.

 

having said that we have no problem running empty no trailer speeds in any lane we want while hitched up so that’s my comfort level goals lol, we get out of town quick and can roll left lane speeds for extended periods to get out of town far enough to get past traffic and then slow down a bit for the long hauls from there

I tow a 35' white box between 6500 and 7800lbs depending on the year, we rent from a place that gets new rentals every 3yrs....

 

"legally" if you get pulled over axle ratings and the corresponding weight slip from a cat scale is the bottom line. it's a little different if you're the cause of an accident but arguably you could also use axle ratings for that.

 

you're gross axle rating is 7,600 lbs with the front axle rating at 3,800lbs leaving 3,800 on the rear.  I use an equalizer hitch, the good heavy duty one typically from the rental place and it's tough because all my weight is in the truck.... i pickup the camper en-route and i don't want to unload my truck.

 

it's do-able but takes some time at the scales.

I upgraded my brakes to ebc slotted rotors and the hd orange pads.

i finally got a GDE tune for my ecodiesel, strongly recommend it for the babymax also.

 

anyways, axle rating is what i go by, it's what truckers use.

That was a good post. Prolly look into liability and legality stuff first! 
 

also on my light trailer with dual axle, brakes on all 4 wheels, 3000 or 3500 lb torsion axles, and brake controller keeps things smooth at left lane gtfoh speeds and stoppy like I’m empty not towing too, so just like driving an extra long empty truck, definitely set up for ‘sport towing’, if that’s even a thing?

 

I have contemplated putting a ‘This trailer pulled by a 4-cyl...Try to keep up.’ Decal on back door of trailer. 😉

every time we go i have to adjust the L brackets because they just aren't doing enough at the scales, but i bring hefty tool box with all the stuff.  these brackets ended up 1 hole up after scaling it.  have to jack it all the way up on a 12" telephone pole block to get the bars preloaded enough.  Unfortunately the cooler and the generator go behind the rear axle.... i try to leave an alley way to roll them forward of the axle but it never pans out.  that is not ideal as you know.  usually i'll move the cooler into the camper... not owning the trailer, you can imagine everything going in the trailer is in my truck less the wife and dogs who drive separate the next day.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      By BDS my HD · Posted

      Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
