gooseneck tounge weight

this question really has nothing to do with a tacoma, but this forum is full of informative people when it comes to this stuff, so im going to ask anyway.

i want to figure out the tounge weight of my gooseneck horse trailer when loaded.(since its a gooseneck the tounge weight is in the bed over the axle).

in theory, could i go to a scale and first weigh the truck with out the trailer hooked up. then hookup my gooseneck with horses in it and pull onto the scale with only the four tires of the truck on the scale. then simply take the weight of the truck with trailer hooked up and subtract it from the weight of the truck when the trailer is out of the bed?

 

That would work!

 

Yes, that would work.
While at the scales, I would also try the truck's front and rear axles alone. Ideally, the goose neck should be centered over the rear axle, which would mean your front axle should remain unchanged with/without the trailer hooked up, and all the weight should be added to the rear axle.

 

The scale house should be able to "Axle" you out without 2 trips....

Full weight,then for the axles.....giving you the weight on each..front, rear and trailer....

Not sure how you carry tack and feed BUT if you bring hay bales they can be moved to change ballast;this will give you an idea on maxiumizing space LEGALLY....

We use this axle weighing; "Bridge formula" for the "Large rigs".....puts the weight across all axles LEGALLY.....that is why you see different wheel set combinations in different parts of the country....
