Generally speaking, 10% of trailer. Then consider your payload. Then it depends on country and state/province and license and all that "stuff".

No... but to be clear...

Weight on what tag? 

The trucks tag specifies maximum weights that can be placed on/behind the truck.

 

The trailers tags indicate the maximum weight that can be carried by the trailer and it's axles.

 

The actual pin weight of a particular trailer can vary based on what you put in the trailer and where you put it. 

 

The key is that when the truck and trailer are loaded as you intend to travel to weigh the combination at a truck scale. 

 

You should get three weights:

1. Steer/Front axle weight

2. Drive/Rear axle weight

3. Trailer axle weight

 

1 and 2 cannot be higher than the corresponding GAWR on the trucks sticker.

 

1 and 2 cannot add up higher than the GVWR on the trucks sticker.

 

3 Cannot be higher than the trailers axle ratings on the trailers sticker.

 

1, 2 and 3 Cannot add up higher than the GCWR on the trucks sticker.

 

To determine the actual pin weight that cannot exceed the 2865 lbs, the trailer would have to be unhooked and the truck re-weighed without it. The sum of 1 and 2 with the trailer, minus the sum of 1 and 2 without the trailer is the pin weight.

Seems pretty common sense to me, a gooseneck and fifth wheel both place the trailer tongue weight in the same location...

 

Camper dealers are notoriously poorly educated (dumb).

 

Never take advise from them regarding what you can or cannot tow, you'd be better off to ask your neighbors cat.

For a 5th wheel, it's more like 20%

The pin weight also needs to be factored against the cargo carrying capacity. Some 5th wheels are pin heavy. Mine is close to 3k on a 13k trailer which is why I have a 3500HD. 

Your pin weight, the hitch itself, the cargo in the bed and the passengers all count against cargo capacity.

I pulled my equipment and campers for decades. You want minimum weight on your pulling rig. You want your trailer to stop itself with its brakes and just a little sag on your truck. That may be different with bumper pulling I stayed away from those. I would use the best hitch setup with weight distribution if I was to use bumper pulling.

Your goose/5th pin per the sticker is 2865lbs. 

 

GM uses 15% of trailer weight to calculate tongue for the sticker.  So 19,100lbs max trailer 5th/goose, 15% of that is 2865lbs (19,100 multiply by 0.15).  

 

So say you bought a 14,000lbs 5th wheel camper trailer, you'd want to keep your pin around 2100lbs, which is 15%.  I wouldn't go less, but if its a bit past that would be okay.  GM says to not exceed 25%.  

 

Conventional trailer hitch they use 10% of trailer for tongue.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      That one looks decent for the price   BUT..I want something that also supports OBDI/1.5. A lot of the prosumer-grade scanners don't have legacy support in order to keep costs low. I believe the Autel does if you go higher end with them.   For fun, I reached out to a local Snap-On rep because I was interested in the 2600. $1895 MSRP, says he can do $1595. That's still a lot, but then again, that's not a horrible discount for just asking out of the blue. Could probably do better if I was a regular buying off his truck, but I'm not.   Not sure if I mentioned but I didn't realize with USED scanners from Snap On that you need to make sure a) the serial number isn't flagged as stolen. On the newer ones, SnapOn can remotely disable the device if it's flagged in their system. And, customer service can tell you if it is, if you're thinking about buying used. B) Make sure it's paid off. If the seller still owes money to the truck or if they financed through Snap On, the device can be remotely disabled until the balance is paid. It's less clear if SnapOn will tell you if a balance is still owed; I didn't make it that far with the used model I was considering. I did read that SnapOn has no way of tracking any "truck financing" deals between the SnapOn rep and buyer, only if they financed through corporate. So there's that extra caution needed.   Still waffling on whether I go with a ~$500ish Autel/TopDon or spend bigger money. The value seems to be in the prosumer brands. I'm not giving them enough credit TBH, actual production repair shops use them daily BUT I'm still allergic to certain kinds of underdog products trying to unseat American companies with solid reputations. SnapOn's scanner isn't wholly made in the US, but it is assembled here and they have US support and probably the most proven/ robust legacy support.   Something to think about. Value, or principles? There's a $1k difference.

      Winter Returned

      By Atlas · Posted

      I'm thankful to live where we don't have extreme weather. We might all be blown to smithereens when Mt. Rainier goes, but 80 is warm enough in the summer and I can generally count the number of hard freezes in the winter on one hand. The cars here don't rust and they don't get sun-baked, either.   We have finished off many of our average 52 days of "clear/sunny" weather, though. Sunsets are coming earlier, the nights are a little cooler. It's right around the first week of September when we get our first warning that summer is coming to a close with overcast skies and the start of "hoodie weather" temperatures during the cooler parts of the day. By October, it's usually time to ditch the shorts. By November, it's mostly raining.

      My point was: If what you are doing works, keep doing it:   But, I will have a talk with AI to make sure their info is more accurate going forward.
