Bet OP hasn't a clue about speed rating of the tires on that camper in tow as he's flying down the hwy........

My tires are rated to 75 MPH. I do however try to stay below 70.

It would be no different than when the dmax came out. They pulled supposidly a 16K trailer with props to fairs etc around the US. Turns out, the trailer alone was the gcw at the time, add in a 6500 lb reg cab dually, and it was close to 27-28K lbs total! That was in 01!
I know a heavy equipment operator that ran down the road at 40K gcw with a mid 00 4500! those were only rated to 26K gcwr. Going over manufactures gcwr is not uncommmon. ALong with being legal mind you!

I can imagine there is a bit of a thrill passing the competition going up steep grades with a heavy trailer in tow. FLT tested the 2017 F450 up the Ike and it took 11.5 minutes. My guess is the new Duramax will pull that same trailer up the grade in just over 10.

We won't find out with that trailer. It weighed 30,000 lbs. and the 2017 Chevy max tow is 23,200 lbs. I don't see them testing something almost 7,000 lbs. over max.

Yeah only the Ford and Ram are rated for that.

When you're cruising at 75 mph,,,,passing everyone,,, uphill,,, with camper in tow,,,, and you look down and notice the rpm's are at 1800,,,, you say to yourself "Self, buying a Duramax dually was a good decision".

Was there something in this post that was supposed to be of value? Cause I couldn't find anything of that merited reading.

I think what OP was saying is he likes his Duramax and it tows effortlessly. It's all the responses that move the topic off the OP's original post. And I like my Duramax for the same reason.

Some of you guys complaining about towing speeds on here must not tow much out west. There are lots of stretches of highway out here where it's wide open with big sight lines and you might pass another car going the other direction every 10 minutes if that. Whole difference scenario than going 70 mph on a busy freeway with traffic.

As far as I'm concerned 75 on an empty highway out west is a whole lot safer than 65 on a busy interstate with traffic back east.

Bingo! 65 out west would take you half a week to get to the next town.
Support big oil! Drop the hammer rubber ducky!

I'm farther west than both of you. Some places on I5 if you are going 25-30 mph! trying to go 65 would kill a lot of folks, cause a mega wreck etc. In fact, I can not legally go more than 60 mph 50-60 miles north and south of me in I5. or 18 miles or so east on I90 from the middle of seattle!
I'll stick to no more than 60 wherever I drive with a trailer....maybe 65 if open as in eastern washington.....legally I can only go 60 if towing a trailer or over 10K gvwr/gcwr!

So you found one highway where due to traffic volume, lower speeds ar appropriate. Good job!
And the I5 corridor is a choked out pile of shizz from Portland to Everett. But the other 1000s of highways west of the Mississippi get pretty boring at 60mph.

What are the lights for on the bottom right? Something wrong with you gauges. Avg. MPG of 13.4 at that speed? Even if it was a result of lower speeds to climb at that speed should have dropped the mpg.

Truck was my 11 HO RAM Dually with 3.42's. Lights are Tow Haul and Exhaust Brake.

I was traveling on I-10 Eastbound towards Phoenix, AZ at 75-80 mph. I slowly ramped up from that speed to 103 over a couple miles and the wife had no Idea how fast I was going.

My 15 will top at 104 @ much higher RPM's.

I've never seen what my 13 or my 16 would do but I have my speed limiter on my 05 set at 109 and it will pin your head to the head rest up to that 109 but it will also break the back tires loose at 55 to. That's with 3:73's :B

Sure you can. :R. Most likely its your transmission breaking loose

truck starts walking sideways......transmission is good.;)
