Spring rates, gross axle weights, etc.

[M'staedt]

Does anybody know what the factory spring rates are for the front and rear springs of a D250 or D350?
How about ACTUAL axle weights (not ratings) for a truck with and without a trailer (goose neck or receiver hitched)? SOMEBODY out there must have weighed their rig at some time or another.

Thanks!
