2020 Chevy 2500/3500 trucks

Hi all,

First time poster, but I've been reading and learning from this forum for a long time. I currently pull a race car with an open trailer with my 2008 Chevy Suburban 2500. It's been a great vehicle with very few problems but is coming up on 300,000 miles. Also in my future may be a new 28 foot enclosed trailer with a bath package.

So... I've been looking at the new trucks. Chevy is my first choice, a Ram may be a possibility, but Ford just isn't happening.

While reading an Edmunds review of the new trucks it stated this:

Putting all of that power and torque to use at very high loads requires a completely upgraded chassis. Here the 3500 HD differs greatly from the 2500HD. It employs a beefier frame, stronger front and rear axles, a 12-inch ring gear, along with beefier universal joints, driveshafts and propeller shaft. And who could forget the extra pair of tires on the dually?

I know that I've read on this very forum that 2500/3500 trucks were the same with the possible exception of a spring or bump stop, but nothing as major as the above would suggest.

First, is the article true? Is it only for the new 2020 Chevy/GM trucks or does it apply to other brands/years of trucks.

Thanks for your assistance - I'll do my best to contribute something of value.
  • Things change. There were times when 2500/3500 trucks were VERY different. Then they weren't and now they're starting to differ again. You can't hold any past rules like that to new designs.
  • This would only be starting with the 2020 3500HD models.

    Previous years the 2500HD, 3500HD, and the 3500HD DRW chassis, frame, etc on GM pickups 2500's thru 3500's were basically the same with very suttle changes which depended on the model built. The 3 OEM builds from the 2500 thru the 3500HD were mostlyjust bolt or purchasable enhansements which added to the truck's capcity, like higher capacity tires or 2 more added, higher capcity shocks, added spring capacity mosty on the rear, and had different badging. Rear axle diameter was the same on all 3 models but the 3500's had an and added cap on top of the rear axle housing on a some year's 3500 models. The rear end/ ring gear etc size was accoring the the selected engine size or type or 2DW or 4wd etc put in the selected truck. So many variations and options were available so can't really cover all the possibilities one could select from in the various size and model level combinations possible as it varied with year.
  • Well I might be able to help. I pull a 28' car trailer. I dont have a bathroom, but **** pissed I dont have one. Mine is tall-too tall actually. It is not what I do with my '18 3500 SRW, Duramax full time, but I do get around a lot with my car trailer. Three trips to California a year and many more trips to Utah and Montana. I pull a ZL1 which weighs spot on at 4K and the trailer weighs about 5-6K maybe a little more with all the extra stuff in it. Not a heavy trailer but it cuts more wind than my Fuzion does without a doubt. My truck is not as tight a new 2020, but I dont use any type of hitch system, I hitch and go. I cant imagine anything you would put in a 28' car trailer that would give a 2020 or my gen an issue.
