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#.

Whoops, your math is off a bit. :) 4" is actually 2.35%. That seems low to me too, mine is about the same amount in front of the rear axle and it puts over 200 lbs. on the front axle, and that's with a hitch weight of about 3400 lbs. Don't know about the math, but that's according to the Cat Scale. :)

4 Divided by 170 is .0235 so it depends on how you are doing the math. Take 6000. X 2.35 the number is wrong. Take 6000. X .0235 and it is 141#.

I have to ask, did you go thru the scales then unhook and go right thru again?

Just going by the math rules: 2.35% is .0235.

I've never unhooked and gone back through, but I've weighed 3 times loaded, and once unloaded, and the numbers are about the same every time. A little over 200 lbs. with a 3,400 lb. hitch weight. Our old trailer with 3,000 lb. hitch weight added over 400 lbs. to the front, but it was the quad cab Dodge, so shorter wheelbase. I'll have to look at the Cat scale receipts when we get back home for exact numbers.
