Towing

I have a 2010 GMC Sierra Denali. 6.2 w/ 3.42 axle with tow package and total gvw of 9300 lb. Looking to buy a 31 ft. Rockwood travel trailer. Gvw 8200 lb.
Will my truck be able to pull this weight?

Pull? Yes. Pull without being overloaded? Probably, if you don't try to haul the wet and loaded trailer, heavy toolbox full of tools and jacks, and a bed load of campfire wood all at the same time.

Your tow rating is a hair over 10,000 pounds. The tow rating indicates the weight of a trailer you can pull with an empty truck with nothing in it but a skinny driver and a tank full of gas.

With a TT GVWR of 8,200, you can expect to load it to about 7,500 for long trips. 8,200 pounds trailer weight is a lot less than your tow rating. So you could load about 2,000 pounds worth of passengers and cargo on the truck without exceeding the GCWR of your truck. And 7,500 TT @ 12.5% tongue weight will have 938 pounds of tongue weight.

938 pounds of tongue weight subtracted from 9,300 GVWR of the TV leaves you 8,362 pounds for the gross weight of the truck before you tie onto the trailer.

So no problem towing that much trailer without being overloaded as long as you don't try to haul a bunch of extra weight in the truck. A normal family of 4. plus a toolbox full of tools, plus normal options on the truck and you should be able to stay below the GVWR of the truck without a lot of hair pulling and concern. Travel with empty holding tanks and minimum fresh water in the trailer and you should have no problem.

However, word to the wise. Use the CAT scale often to be sure you don't exceed either the GVWR or GCWR of the truck, or the combined GAWR of the trailer. Hook up with a quality weight-distributing hitch, such as a Reese Strait-Line, Equal-I-Zer, or Blue Ox. Then enjoy RVing.

IMHO that is a lot of trailer for your truck. Expect to need a really good WDH with very good sway control. Sway will happen when you reach highway speed or when a tractor trailer passes you.

I have to disagree on that trailer being too much. I think with the new 6.2 and 6spd it'll pull very nice. I think it'd do better with 4.10s but keep it in 4th or 5th it'll pull great. A good wdh is a no brainer with that trailer so don't skimp. I pulled our 35ft 9200lb TT with a 02 yukon xl 2500 8.1L and it held the road no problem with my equalizer 4pt. Gas mileage was horrendous so that was my only complaint. However, my mega cab cummins makes it feel like I'm pulling a utility trailer and golf cart lol.

As stated, fuel mileage is why I let the yukon go. 8mpg vs 14mpg towing and 14mpg vs 19mpg highway is a pretty significant difference. I also said the diesel does pull even better. Let's put it this way, I think that truck is adequate

I agree. That 6.2 will do fine. Watch your weights. Use a scale. Maybe look into LT tires if you plan to tow a bunch. Good WDH.

I believe 3.42 is the lowest that comes with the 6.2 GM. My father's boss and co-worker both have one and really like them. Lots of power on tap and damn good mpg.
