so i built a spreadsheet that will do the math for you given the wheel base and overhang.

I also have a section that will calculate for a goosneck/5th wheel. (although, it is not really all that helpfull, all but a few pounds go to the rear axle on a goosneck)

I'd post it up for everyone if i knew how, but i can't figgure it out.

mods? any help?
