New Andersen WD hitch

So your saying that a 1/2 ton with a 7200lb GVW that squats 2-1/2" with 900lbs on the hitch is the same as a 1 ton dually with a 14,000lb GVW that squats 1/2" with the same 900lb TW?---

I can't answer your question because I don't know what you mean when you say the 1/2 ton "is the same as" the 1 ton dually.

I can say that if the trucks have the same wheelbase and the same ball overhang, the 900# tongue weight will cause the same load to be removed from the front axles and the same load to be added to the rear axles for the two trucks.

If the 1/2 ton squats 2-1/2" and the 1 ton dually squats 1/2" for the same amount of added load, that means the rear suspension for the 1 ton is 5 times as "stiff" as for the 1/2 ton.

If we assume the trucks both have a 150" wheelbase and a 60" ball overhang, the 900# TW will cause about 360# to be removed from the front axles and about 1260# to be added to the rear axles.
For both trucks, the WDH must add 360# back onto the front axle to return the front load/height to the unhitched values.

---I just don't see how you would need to put the same tension on the bars/chains to return to the same fender hiegth. If I only needed to bring the front down 1/4" as opposed to 1-1/4" your say it would be the same exact setup on both vehicles. Then why do guys use different settings with their trucks and TT's? Some guys need (Eaz-Lift for example) 4,5,6 washers, some are 1,2 or 3 links hanging.

They use different settings because their trucks and TTs have different wheelbases, ball overhangs, and tongue weights.

I was always under the impression that unless the front of the TV is raised then no weight is being removed. The more the amount it raises the more is removed. Is that right or wrong?

It is correct that the front will not raise or lower if the front axle load does not change.
If load is removed from the front, the front will rise.
The amount of rise depends not only on the amount of load removed but also on the suspension stiffness.
The amount of load which must be added back via the WDH depends only on the amount of load removed by application of TW -- it does not depend on suspension stiffness.
