I have never checked to see how much weight is transferred to the front axle on a gooseneck or RV. That said I run heavy, not so much with the TH but with a gooseneck. I am licensed to 40K and typically right on that in combined weight ('20 3500 DRW). I am struggling to believe that such a small amount of weight is transferred to the front axle. It just doesn't seem possible. The differences between the trailer weight ratings between tag and gooseneck on all the HD OEM's just makes that a leap for me to believe. The way the truck sits when loaded heavy between the two types of trailers says there is more than a couple hundred pounds on the front end with a gooseneck. I don't have data that supports what I am saying, and I probably should have, but when I run over scales which is typically at gravel pits, I just look at gross combined. DOT has not hassled me so I run with that.

It's very easy math to figure your weight transfer to the front axle. Measure centerline rear axle to centerline front axle. Now how much forward is centerline of kingpin or gooseneck ball from centerline rear axle.

My axle to axle centerline is 170" and forward dimension of kingpin is 4" that is .0235% of 170". My pin weight is 6,000#. .0235% of 6,000# is 141#.
