2016 3500 HD SRW duramax
My towing capacity is 17,200 and payload is 4000 lbs. I was planning on getting airbags
I am thinking of buying the keystone carbon. Dry weight is 12,700. Max is 17,000
Everything looks good but wanted advice on this before I purchase something like this. Any help?

Air bags do nothing for payload.

Re: 2016 3500 HD SRW duramax
Lot of trailer for a SRW. I'm guessing it's the 357?
With a GVW of 17000 and a pin weight of 25% you will be at 4250 vs a 4000 payload - just to start; no hitch, no people, no stuff

Re: 2016 3500 HD SRW duramax
Good to know. So looking at hitch weights at different fifth wheels the percentage of hitch weights changes per model. (Using dry weight stats) some look to be as low as 20%. Also with toy haulers a lot of the weight besides liquids and stuff will be in the garage. Toy weight is 1300. So using the percentage based on dry weight to calculate fully loaded pin weight confuses me.

Re: 2016 3500 HD SRW duramax
Like for example the 357 dry is 12,500 and hitch is 3000 roughly. If I put the 1300 in the garage would that decrease hitch weight.

Yes but not by the same weight. I don't know the formula or even if there is one.

Re: 2016 3500 HD SRW duramax
Others will chime in on this I'm sure but .....
The dry weights of the 357 put the pin weight at approx. 24.48% of dry weight. Optimally, that percentage would then remain approx. the same as you loaded to GVW. You can reduce the pin weight by loading anything and everything in the back; I suppose you could reduce it to 0; but you just wouldn't be able to pull it and control it.
As far as I know the accepted parameters for the hitch weight on the 5th wheel should be somewhere in the 20-25% range; from my experience I think it tends to be toward the 25% mark. You need that weight to stabilize the towing of the trailer/truck combo. Some feel that everything works great at around 20%, others want more.
Regardless of how you slice it, if the trailer is loaded properly, I think you are going to be overloading the truck or very close. Others may have different opinions and they will comment so hang on...and keep reading
When getting to that size of trailer you did the right thing by just asking - the smart thing. Whatever decision you make you will make it with your eyes open - can't ask more than that.

What is the index tire rating you have on your TW? I have experiance 3000 lbs is nothing on my 2500 The only reason I have 5000 air rite air bags on my 2500 it dont have the overload springs even before the bags the sag was margina its nice to know your not weaking the springs with bags. I now load everything in the back and its easier on me. With the garage empty I can feel the pin weight a lot. When loaded I Im at 10500 lbs on the rv axles cat scale way under the sailun 14 ply tires. My 311 is 16000 GVW witch would be impossible unless you where hauling lead because 2700 is on the truck.

E tires are standard Index load is stamped on the tire telling how much weight the tire will carry I expect your tires are at 3700 lbs each.

Re: 2016 3500 HD SRW duramax
Loading heavy in the rear won't affect the pin weight as much as you think. I filled my water tank (at the very rear), 63 gallons-400+ pounds , weighed at a CAT scale, drove around to the parking lot and drained all the water. 45 minutes later when the water finally drained I re-weighed. I think I lost maybe 100 pounds off the truck rear axle.

Re: 2016 3500 HD SRW duramax
Something to consider if you do all your calculations with the ATV/motorcycle loaded in the garage. That's 1300 pounds of "counterweight" to the pin weight. If you have to rely on that to keep your pin light enough to not overload your truck, what are you going to do when you want to tow your trailer "without" the ATV/MC ? There will be a number of times when you'll not want to take the toys, or you'll want to use the garage for a bedroom when going somewhere where you won't be using the ATV/MC.
So, when doing your pre-purchase planning, don't rely on always needing to load the garage just to stay in the ballpark.

Hmmm, what kind of 2500 do you have? What does the door sticker say? 3000 lbs pin weight "is nothing" ....on a 2500? Not trying to be argumentative but the OP is looking for safe numbers.

I have a 2016 gmc 3500hd crew cab 8 foot box 4x4 duramax. SRW...I think my truck payload is roughly 3800. So minus people stuff and hitch I think I have 3100 lbs left.
So what I need to find out is on the manufacturer website when they list the hitch weight of 3000lbs is this based on the the UVW or the GVWR.
Thanks for your help guys!!!

The dry (unloaded) pin weight of the 357 is listed at 3060 lbs. This will go up significantly when loaded.
