Well, it's cuz the fat hips the dually has, makes parking more of a hassle, residential streets with parking on both sides, stuff like that.

And never, ever let your wife/girlfriend drive it anywhere except for an empty parking lot, almost 100 % guarantee fenders will be missing otherwise.

I currently have a 2016 1500 LTZ/Z71, 5.3. I tow a Jayco 28 ft. (6500 lbs loaded) TT  The truck struggles to maintain 60 mph (flat land) 

I agree that a 2500/3500 is a good choice if regularly hauling a substantial trailer.  However, I believe your current truck should do better than you describe.   Perhaps you have a 3.08 gear ratio?

My 2020 Silverado 2500HD pulled my 9500lb TT great and returned around 8.5 mpg. Now, it tows my 42', 14,300lb 5th wheel and does fine with that as well. I'm around 7.5 mpg towing that, vs the 8.5 towing the TT. Not too bad for that much more camper. I have the new 6.6 gas engine, also.

GU6 code in glove box = 3.42. I think that was the only option with the 8 speed transmission.

fwiw, with the 8 speed, 3.23 was the standard rear end, 3.42 was what came with the NHT (Max tow)

Hmmm interesting. maybe it also came with Z71 package? I don't think i have max tow. But I know It's 3.42 diff.

I had a '17 NHT maxtow 6.2, pulled 8800# TT, NY to FL couple times a year. Did the job well and was a blast to drive when not towing too.

Traded for a 2500 Duramax Denali, it didn't even know that trailer was back there.

Then traded for a fifth wheel........had to air bag and increase tire load ratings........

Now traded for 2020 3500 AT4, It has a nicer ride than the '18 Denali did......

 

Catch where this story is going..........go drive a 3500

Max tow will have NHT code on the glovebox label.

 

Does the truck have tow mirrors?

Nice!! This is exactly what I was hoping to hear. You obviously did not regret going up to the Duramax 2500 even though you had a more capable truck for pulling than mine with that max tow 6.2l.  I plan on test driving a 3500 very soon.

Thanks!

It did not come with tow mirrors, I added them later. NHT is not one of the codes in the glove box. But GU6 is on the list which is the 3.43 diff. So it must have also come with another package other than max tow.

I agree. I pulled my 28' camper with my 2013 1500 LT with 5.3L and it would run as fast as I was comfortable going down the highway. I added air bags to the truck when we had a big pop-up camper and really liked having the air bags on the truck. They weren't really that necessary with the 28' camper and weight distributing hitch and sway bar. Towing in the summer was easy, it was towing in the winter with my new 29' long aluminum snowmobile trailer that make me upgrade to a 2020 2500HD with the 6.6L gas engine. I only tow in Michigan, so no mountain passes, but it is a very capable truck and rides great as a daily driver HD truck. I never got that great of gas mileage with my old '13 1500 anyways, so my new HD's mpg isn't that much of a difference and I only drive it around 12-14K miles a year.

I would/do  pull a 6500lb trailer through the mountains with my 4.3 V6.   My current trailer is shorter than Op's but about as heavy when fully loaded.  I will not intentionally drive an overloaded truck and trailer combination but there are very few configurations in the 1500 lineup that would be overloaded with a properly attached 6500 lb. travel trailer.   I would love to buy/drive a 2020 GMC 3500 as a daily driver if affordability wasn't an issue!  95% of the time I'd use it to haul around my 18lb Pomeranian cross looking like I was about to pull something heavy! ?

Ok... Explain this because It will be a Daily driver..

 

The other issues others didn't mention is if you get a SRW you'll more than likely get the short bed (for some reason people love that thing) vs a dually that will come with the nice 8ft bed.  Longer truck means bigger turn radius.  If the truck has the tow mirrors on it then the mirrors stick out farther than the fenders.  Makes it easy to know if the butt will fit when driving through something, mirrors hit butt will most likely hit.  DD a dually is no where near the scary proposition that seems to be said over and over on the internet, especially this forum.  If you cant' drive a SRW then you can't drive a dually either.  As far as the 2500 vs 3500 SRW unless something has changed on the new ones the difference in empty ride quality is negligible.  3500 SRW is basically just a 2500 with an overload leaf when ride quality is concerned.  Previous years used to have a couple differences but none that really did anything to the ride.

Good info thanks, It really looks like it makes more sense to look at the 3500 SRW due to more capability and negligible price and ride quality difference.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.
