WD Question For Ron
If you have a conventional tow trailer with a tongue weight of 1000 and with a properly adjusted WD, 300lbs is transferred back to the steering axle and the remaining 700lbs is transferred back to the...

In theory, to achieve 100% restoration of the load removed from the front axle,
the amount of load transferred to the TT's axles is a function of:
1) the distance from the TV's rear axle to the ball (call this D1), and
2) the distance from the ball to the midpoint between the TV's axles (call this D2).
To achieve 100% restoration of the load removed from the front axle, the percentage of tongue weight transferred to the TT's axles is given by:
Percentage = 100 X D1 / (D1+D2)
For a typical value of D1 = 65", the percentages for various values of D2 are given in the following table:
D2 (inches) Percentage
-----160----------29%
-----180----------27%
-----200----------25%
-----220----------23%
-----240----------21%
-----260----------20%
I agree that percentages obtained from scales data tend to be closer to 20% than to 25%.
This suggests that, in many cases, front axle loads are not being returned to their unhitched values -- either intentionally or unintentionally.
