Percent of Pin Weight on Each Axle

My question is a technical one.

If the fifth wheel hitch is installed where it is recommended, which I understand is several inches in front of the rear axle -- How many inches is correct, BTW? -- What percent of the Pin Weight will be on the rear axle and what percent on the front axle? I realize the % on the rear axle is very high, 90 or 95% or more perhaps, but I would like to know what that figure generally is.

You can't can't calculate it without knowing the distance between the axles (wheelbase). But it will only be a couple of % at the most. By the numbers it would be x/(wb-x) where x is inches in front of axle and wb is wheelbase in inches.

If you want to calculate the factor the front axle is unloaded by putting the pin behind the rear axle use x/(wb+x).

For all practical purposes, you could use x/wb in either case... You'll find a couple inches either way really doesn't make much difference.
