Anybody looked into towing weights on these trucks? Dealers don't have much in the way of info yet. Looked at a 4500HD CC 4X4 today-- very nice truck. We are thinking of trading our Pete 337 and the 2019 3500HD in on one if we can figure out which model will haul a 23K GVWR GN horse trailer safely. Anybody have any thoughts or opinions on this?
Come on Hook-em, help a fellow Texan out-- I know you probably know this stuff

Wife doesn't like driving it and refuses to get her CDL for it. Me personally I love the truck. A little bit of overkill with our trailers but sure is nice to know it is up to the task. She says if we get one of the new medium duty Chevys she will get her CDL for that because the interior and controls are just like her 3500.
From what I can figure from what GM has published, I believe that a 4500 will work. The 8 horse has a hitch weight of 3450 all loaded to max GVWR of 23K. The 4500 with the 430 rear is good for 34K. Truck curb weight is going to be around 11K after a flatbed is installed.

You may want to wait for a 2020 as the towing weights are improved significantly. A 2020 3500 may do the job well.

Not a bad Idea Henry. Wonder when the specs will be published for the weights. All 3 models use the same frames/engines etc. GM uses different trans and rear gears and some suspension changes to accommodate different weights. I would have thought the 4500 would have a higher GVWR. Not that much more than a 3500-- just better built for the weight.

4k lbs isn't much of a difference?

The advantage to the MD vs the 3500 has always been the load carrying capacity. Not so much in trailering. In fact, based on their published specs, many times it has less towing capacity than the 3500, but it will handle a much higher pin weight. Of which, the two go hand in hand.

Depending on what rear end/trans you choose, looking at the spec sheet for the MD, it shows GVWR of 15k / 16k / 16.5k
with a GCWR of only 26k / 30k
I suspect that 30k combined is NOT with the 4:30 rear you drove.

You're projected empty weight of 11k, only leaves 15k / 19k for a trailer...per the specs, towing less than the 3500.

It's not the same motor in the MD as the 3500....several things are different; turbo, lesser tuning output, etc.
As well as a different transmission too (depending on your option selected).
It's designed to get the load moving off the line.

Which is what the 2020 3500 is claiming with the 10-spd paired with the 3:42(?) rear vs the std 3:73 for the last 19 years....getting the load moving with ease.

30k trailer wont be an issue behind either of the 3 4500/5500/6500 chasiss..
I have a build sheet for a 6500HD with RDS2700 Allison 4.30 gears and 225/75/19.5 should put cruise @70mph [email protected] rpm
I was upper 60K for a RC 2wd 23.5K truck.. 4x4/CC pushing 80k
the print out is 22,940 GVWR with 8k/15.5k axles and a 26k GCWR.. big face palm. the dana S16-130 rear axle has a 50,000lb GVWR same with the RDS2500/rds2550 is the closest listed for 30/33k... that's off Allison's website...
IMO GM jipped us on the numbers game... and they have been doing it for a while now

I looked at a 4500 with a 7500# front axle(standard on a 4X4) and 11000# rear. It does have the 430 rear set. Trans is the A1750HS.

The truck I am estimating will weigh 11K curb( all loaded without trailer) It is a CC, 4X4 cab-chassis and weighs 9100#. Still have to install a flatbed on it.

As for the engine, it is "detuned" from the L5P to 350HP to meet emissions requirements for this class of trucks according to GM literature.

Too bad you can't get air susp. on a 4X4 even on just the rear.

Too bad it has to be registered/insured as a commercial vehicle. I'm anxious to see how the 3500 dually's fair.

Here in Texas we can register it as a farm truck. Did that with the Pete. But the normal insurance carriers wouldn't touch the Pete so I went with Progressive and to insure it and the 8 horse trailer is 1628.00 per year.

I expect it will be about the same with a new 4500 although it will have less weight capacity than the Pete so maybe less I hope.

Why would you expect the 3500's to change? My 2019 3500 is good for GCWR of 31300 already. Which ,by the way, puts it in CDL required.

GCWR goes up to 43,500

Is that for the 3500? Seems like alot of weight for a one ton truck.

Well, I got the 2019 CC 4X4 4500HD cab and chassis. Still needs to get the flatbed installed and bedliner sprayed on that. I have to put my trailer camera wiring harness in it and the monitor in the cab and supply power from the batteries to the disc brake hydraulic pump on the horse trailer when I get the truck in my hands.

Just for info: the front axle has manual locking hubs-- with an electronic shift in the cab. Trans is the Allison 1700RDS, 430 rear, and 11K rear axle. Build sheet shows GAWF as 8K and GAWR as 19K. Door sticker has 7500/11K respectively. Not sure how or why they did that.
It has the Duramax L5D. The 50 degree cut on the steering tire on the left side is great to get to the engine, but forget the right side-- too much in the way.

Truck drives nice-- like a 3500 on steroids!

I took delivery of the 4500HD today. CM flatbed was installed and I always have the bed and headboard rhino lined to keep feed sacks and such on board. What a nice truck! Not alot of difference in ride quality from the 3500HD we traded but we prefer that type of ride.
One thing we noticed right off-- when you step on the brake pedal without the engine running it has an electric pump that comes on and stays on as long as you press the pedal.
You can only get 2 trim levels: WT and LT which is the one we have and both come with the vinyl floor covering. It is a 199" W.B. with 84" cab to axle with 49" behind that. Makes for about an 11 FT. bed.
It has 19.5 X 6.5 ALcoas with Goodyear 225/70R19.5 14ply G rated with almost 4K load rating. The 7500# front axle is a manual locking hub type made by Dana/Spicer. Truck also has the electronic transfer case shift in the dash.
Engine is the Duramax L5D: 350HP and 700 LBS torque. It seems just about as peppy as the L5P in the 3500. We'll see when we hook it up to the trailer how it works. Still have to install the rear view camera in the headache rack to see the hitch and wire the truck for our trailer cameras.
