Duramax 2500 too much vehicle

[mefly2]

We are pulling a 25 FB with a 3/4 T 2500 and have already found popped rivets ... not sure if that speaks to AS QC or the stiffer suspension of the 3/4. Approaching 10K miles on the Cummins and still very POOR fuel economy. When the warranty is up there are other options for increasing the economy.

We had about 4 or 5 popped rivets in the first year or so. All but one were in a line over the kitchen counter. When I tried to replace them, the correct size would not work and I had the impression that they were not in a proper place and weren't holding anything. I used the right sized drill bit to drill the old ones out, so that wasn't the problem. I ended up putting new ones, a size bigger in, and they have stayed in since.

By that time I had Centramatics and not too long after, put on Michelin tires—they ride better than most tires. I haven't had a rivet pop since.

So my popped rivets could have been from poor QC or a trailer that didn't ride as well as it did after I added Centramatics and better tires. I also readjusted the hitch about a year or so after we bought the trailer. And in your case, it could also be the 3/4 ton truck or the hitch.

So, it is hard to know just what the cause is.

We had a couple of hitches with very stiff w.d. bars/chains (Equal-I-Zer and Andersen) and had popped rivets even with out 2012 Ram 1500 with rear coil springs. Put on a ProPride with more flexible tapered 1400# bars and no more trouble (yet).

Inland Andy is a supporter of flexible hitch connections to prevent trailer damage, and I'm becoming a believer. Maybe that would be a good starting point.

I have been pulling with 2500HD diesels since 2005 and have never popped a rivet. First hitch was a Reese HD cam with 1000# bars. After 3 years, I remounted the Reese head on an AirRide hitch. For the last 18 months, I have had the PP with 1000# bars.

I used Centramatics, but when I put the pretty 16" wheels on this year, I didn't like the look and took off the Centramatics. The Centramatics made it very difficult to check wear on my disc brakes.

This thread is many years past but was looking here other 2020-2021 GMC / Chevy 2500 owners and the experience towing your rigs with these updated designs, technology and increased payload models ? Also the newer Gas or 6.6L Duramax and overall performance?

F-250 Super Duty chiming in to the Duramax thread..... you can never have too much.

I bought my 2021 in December of last year with the diesel and Allison. We are moving up to a 25 GT from a 20 FC. Still waiting on the 25. But with nearly 6 months on the Denali I am glad we jumped early. I am STILL finding out about stuff on it. And though it has not been on a lot of highway yet, when it was the mileage was unbelievable for the enormity of the truck!

So far I love it.
