Towing Capacity - 2016 Silverado 2500HD 6.6 Duramax Turbo Diesel, Crew Cab SB 4WDrd Bed


Asked by Feb 21, 2017 at 02:36 PM about the 2016 Chevrolet Silverado 2500HD LTZ Crew Cab SB 4WD

Question type: General

I am totally confused when doing research on what I can tow with my truck.   What is the max king pin weight?  I am told 18,000 total weight but when you look at calculators and subtract the weight in the truck and passengers (4), it calculates only a 9K - 12K 5th wheel max weight and our 5th wheel we bought is 13,400 dry.  

How do these trucks have the ability to pull 18K?  Again, I don't think I'm an idiot but I just cant figure this out! What am I missing? HELP!

Hi Ken, I appreciate your question as my husband and I are having the same problem. We have the same truck as you except we have the 8' bed rather than the 6.5', and we are having a hard time determining what size 5th wheel toy hauler we can get. The 2016 Chevy towing guide says 12,900 but the 2015 trailering guide for our truck is 16,500. Seems strange that it would drop so much. 2016 Trailering Guide nscwebsite/en/Home/Vehicles/Commercial/02_PDFs/MY15- Trailering-Guide.pdf 2015 Trailering Guide scwebsite/en/Home/Vehicles/Trucks%20and%20Vans/2016_Silvera do_1500/Overview/02_pdf/MY16%20US%20Trailering%20Guide_0 60816.pdf


Our guide says 17,700 lbs max towing capacity. I'm assuming that is total weight the truck can pull but is that all weight for the 5th wheel or 5th wheel and truck? I just don't know. And is it recommended or maximum? Sometimes, things are rated but can actually pull 25% or more than the rating with no problem.


I am really stumped because I thought this would be the place that could answer my questions but I guess not. :( Therefore, I have done my research and here is what I found out and please chime in if I am wrong! In my Chevrolet 2016 Duramax Diesel owners manual Supplement, page 65, "Driving and Operating" section there is a table that gives you max trailer weight, max tongue weight and Gross Combination Weight Rating or GCWR. For this truck, the GCVR is 25,100 lbs. What that means is the total weight of the truck (including occupants), trailer (in this case 5th wheel) and all cargo in both the truck and the 5th wheel. My 5th wheel is 13,425 lb and my truck is about 7,300 lbs so that leaves me with about 4000 lbs give or take of cargo and people in the truck and the 5th Wheel. I know the 5th wheel is going to be a little hard on the suspension so I am going to install airlifts to help with towing. Tell me if I am wrong...

I would run your VIN and see exactly what is specified for your truck. Towing capacity is the trailer weight plus cargo and passengers, Not the truck weight.

I think you are right Ken. It is a good idea to weigh the trailer and truck to see the total weight. Keep in mind that the trailer may end up a lot heavier with cargo and the tanks full.


How do I run a VIN to see towing capacity? The truck has 410 gears and I believe that makes a difference.

This is one VIN checker but there are others online -----

The VIN checker still only provides general information. Where else can a person get the facts on their particular vehicle.

No answer here same problem though My 2016 Chevy manual only has specs for the gas V8, and is confusing. I never received a supplement for duramax? Am looking for 5th wheel, so I plan on keeping it under 14000 pounds and 2600 pin weight. Nice to know I am not alone in the confusion.
