Help with Towing Calc

Do you have a photo of how your hitch it setup? Is the yellow sticker on the hitch facing forward or aft? Your numbers indicate the pin is aft of the rear axle. With the same hitch I defiantly add weight to the front axle in the furthest forward position.

I come up with 3,400lbs of pin weight. 12,180 GVW with the trailer and 8780 GVW without gives a difference of 3,400lbs which would all be pin weight if the truck had the same cargo/fuel/passengers.
 
What specific model Companion do you have?

For the GN attach Companion, there's also a socket "post" position that's possible.

If you have the 3600 puck hitch as described in post #70, look carefully again at the diagram and cab direction and where the arms are mounted.

You are fine with the rear weight the tires can take more than the load rating without failure ( not recommending you exceed just stating a fact) so its not like you are in the danger zone
 
Here is the hitch. IMG_3153.jpeg RVK3600 is the model I believe. I can't see where there is a "post" position but it appears I am either directly over the center puck or maybe 1 inch forward of it if that means anything.

Not sure. The king pin disk is about 13" to the underside of the trailer. The flat portion of the B&W hitch is about 2 inches below the bed rail. So I am guessing my bed rail to trailer height is somewhere around 10" to 11". I'll be hooking up Sunday and will take a better measurement. This could be a reason for weight coming off of the steer axel? What should the bed rail to trailer height be? BTW, there is hitch is in the medium position.
 
AH64ID. If my trailer weight is 12180 with a pin weight of 3400, so I am looking at almost 28%? Wow......is that correct? My sticker is facing forward to the cab with the BW logo facing rear.

Sounds like maybe the hitch is too high.

The trailer should be as close to level with 7-8 minimum bedrail clearance unless you intend to offroad it. If I have to choose 1/2-1" either way, I prefer slightly nose high on a 5th wheel but I don't run TH's so maybe in that case low unless loaded.

That said, everything looks OK front to back so probably just scale variance. You should def not be taking weight off the front with that setup.
 
Everything looks correct for the hitch. Must just be scale variance, but it is consistent.

12,180 is the trucks GVW with the trailer attached.

Trailer GVW is 14,540.
 
Did you have your foot on the brakes or were you in park with everything "relaxed" when you last scaled?

Were the front and rear truck axles (mostly) centered on the separate pads?

Same scale?

You could always do more than one reweigh and put your front axle on a different pad.

Anyway, I'm sure it's fine. The hitch is correctly mounted where it should be.
 
Thanks Brutal. I plan to reweigh tomorrow on a different CAT scale. I will wait until the truck/trailer settle in park before I start the app.
 
I stopped by the CAT scale today. Gassed up, pulled up on the scales, fairly centered on the steer and drive pads, and put in park. Waited a full minute before I dialed up the app. And this is what the numbers were:
Steer - 5300
Drive - 6640
Trailer - 11340
Gross - 23280

In Post 80, I listed my previous weights. Of note, my initial weighing on Thursday (9/19/24) is significantly different in the steer and drive numbers but the Gross is 40 pounds lighter. That could be the beer and food we consumed. :) It appears I have some bandwidth and not as close to being maxed out on the truck/trailer. Based on my initial truck only weight (8/31/24), I have a pin weight of 3100 pounds (6640-3540) now? And the trailer is coming in at 14,500?

And to follow up on the height of my bed rail to trailer height, it's at 9.5" at the pin. Here is a pic of the truck/trailer. A little nose high? Should I drop the hitch 1"?

944651CA-5068-4D41-AD01-F7AF95CCAE10_1_105_c.jpeg If I drop 1", will that change the drive and steer weights?

I appreciate everyone's help!!!!

Does that connect to the pucks?

Also look at Trailer Saver . They are also air ride and yes they do connect to the pucks , but they are heavy . I have had mine for 12 years . Never an airbag problem and yes they are expensive . So is that trailer .
