The owner's manual is very vague when it comes to using a WDH. It essentially states that a WDH is not required at all unless using MT or OOR tires, then only after 10,000#s. What are OOR tires anyway, AT tires? I've never heard tires called that before...

 

Anyway, then looking at the trailering info on my door it states that my tongue weight limit is 1450#s. Ok, but if using a WDH doesn't that increase the maximum tongue weight to around 2000#s? If not, then there are 3/4-ton trucks out there with much higher allowable tongue weights than our 1-ton trucks. 4k# payload but 1450# tongue weight?

 

I'm looking at conventional hitch toy haulers and most of them are already close to 1450# dry tongue weight and some are over that. But according to my door sticker my "1-ton" truck can't tow them.

 

What gives?

I'm just going to assume that so long as the tongue weight stays under 1450# as shown by using scales then I'm good to go.

 

A WDH will transfer some tongue weight to the axles on the truck and the trailer, and it will show on the scales. But the amount of weight transferred will depend on the WDH and on how well it was installed. I guess GM doesn't want to give blanket numbers like other manufacturers. But they could state it like I did above so people don't get confused like I did. Other vehicles I've owned stated dead tongue weights and distributed tongue weights.

 

A 1-ton truck should be able to tow any conventional hitch trailer IMO.

Remember the manual covers DRW trucks, which is why it mentions up to 20,000 lbs. For an SRW 3500, the maximum conventional trailer weight is 14,500, and max tongue weight is 1,450.
 

In my opinion there is no need to use a weight distributing hitch on a 3500hd SRW at all.  The hitch tongue weight limit is 1450 for an SRW, and the payload of the truck is typically about 4000 lbs.  

 

For a 10,000 lbs trailer as an example:  Without a wdh, with 1000 lbs on the hitch about 4 feet behind the rear axle, you are putting about 1200 lbs on the rear axle and taking about 200 lbs off the front axle, are fairly close to an ideal 50/50 front/rear weight distribution, and haven’t even “leveled” the truck yet even if you carry another 600 lbs in the bed. 
 

A big benefit of not using a wdh is you are less likely to overload and fail your trailer frame going over dips, driveways, or sudden transitions to a steep incline.  
 

Every pound you pull on the WDH chains is reacted by the ball, and significant additional bending load is added on the trailer A-frame at the front of the trailer due to the torque from the wdh. That is where you will sometimes see frames bend or break.

But it makes no sense to limit the tongue weight to 1450#s. Dual wheels or not, it's the same frame. The tires, wheels, axles and suspension on a SRW are more than capable of holding more than 1450#s or else the payload would have to be less. Weight is weight, no matter where it comes from. The class V hitch itself is good for 2000#+. It's the exact same hitch and frame on SRW, DRW, Gassers and Diesels. DRW are needed to support the tongue weights of heavy 5th wheel and gooseneck trailers, which can get much heavier. Chrysler and Ford tongue weights are much higher for their 1-ton trucks (1800#-2700# on class V hitches SRW).

GM also does not have the tongue weights listed anywhere I can find other than a sticker on the truck (Chrysler and Ford is no problem). This is complete BS since a 1-ton truck should be able to tow every conventional trailer available. People buy the truck expecting to tow something since the trailer weight is well within limits and then find out the tongue weight limit is pathetic. There are conventional toy haulers out there with a dry tongue weight of 1600#s. I know people whom have a conventional toy hauler with a 1900# wet tongue weight.

Also, on some trailers having 10% of the weight on the tongue is not enough. It's fairly common to need 12%-13% for a smooth ride. That reduces the towing capacity down to around 11,000#s instead of 14,500#s.

I don't want to use a WDH, but I'm going to use this truck for the reason I bought it.

For me this is where things start to get into a gray area in my mind.  You are absolutely correct of a WDH putting more stress on the trailer frame.  I use one with our camper but it's a WDH with sway control bars, not the chains.  I haven't tried towing our camper which has 1k tongue weight and another 7k on the axles without it.  I might just try it out because I've read horror stories of the front frame on campers bending and cracking due to the use of a WDH.

I’m only familiar with some of the wdh and antisway systems out there, so I don’t know exactly what you are describing. Maybe a photo or product name?  I’m just curious to learn more. Thanks. 

This is the one we use.  https://www.etrailer.com/Weight-Distribution-Hitch/Fastway/FA92-00-1000.html

 

But I'm still curious as to how our camper would tow without using it.  I bought a fastway 12k hitch the other day.  I think I'll try just using that on our next outing to see if the WDH really makes a difference.

Here’s something interesting.  My 2500 is rating for a heavier gooseneck trailer and high hitch weight on a gooseneck that the door sticker posted above.  Bumper trailer rating is the same.

That is correct.  The towing limits and tongue weights are higher using a 5th wheel.  Here's my sticker, same as yours.

Sorry if I came off a bit abrasive. I was a little upset when I was posting last night. I meant no offense to anyone here.

 

This is one of the toy haulers I am considering. As you can see the dry weight is way under my towing capacity, but the tongue weight is really close to my limit. This is the shorter one of the bunch. The longest one has a 1600# dry tongue weight. I do not like being so close to my limits when the trailer is dry.

 

Now, with toy haulers the "toy" gets loaded in the rear and that will reduce some of the tongue weight. How much depends on how much weight gets added to the rear. But there are variables which will constantly change as well. Such as this trailer has a 100 gallon water tank. Whether it is full or empty is going to change the tongue weight. If that water is in the black and grey tanks it is going to change the tongue weights. The trailer has a 40 gallon fuel tank too. How much weight is stored in the front storage area, as well as other stuff stored in all areas of the trailer is going to change tongue weights. The list goes on.

 

The point is, there are times when it's entirely possible to be a few hundred pounds lighter or heavier than the dry tongue weight. I plan to adjust rear weight as needed to keep my tongue weight in spec.

 

However, what if I wanted the 29TRX? It's dry weight is also under 10k#s. That's well within my towing capacity. But the dry hitch weight is 1600#s. So, while I could add my toy to the rear and probably get the tongue weight under 1450#s, I couldn't ever tow the trailer dry without being over the limit. Hence my anger. I would like the larger trailer, but It's too tongue heavy...

I commend you for doing your research on the weights.  So many times people are out there saying...oh yeah, my ford escape tows 12k pounds no problem....lol....but seriously I do commend you for trying to figure out the weights to stay within the ratings of your truck.  That makes you a safe guy!!  I love that!!
