Let me rephrase that, I think it's more important with a tandem axle than a single axle to use a weight distributing hitch. The tandem axle carries more of the weight on the front axle when the trailer is nose down and you can overload the tires if it's too much out of balance. The weight distributing hitch distributes the weight evenly across the two axles. Of course, the tow vehicle can be out of whack too if it's nose is too high; not enough weight on the front wheels to steer and the weight distributing hitch helps with that too. It's easier to move weight around inside a single axle than a tandem to hit the tongue weight you want, especially if you are in the building stages. So it's not that you don't ever need a weight distributing hitch with a single axle, it's that you can probably distribute the weight in the trailer so that you don't.
