Edit: and I've now read the thread posted earlier on WDH and I now get how the weight on the rear axle can make the rear lower, just as my manual states the rear of my vehicle will drop up to 1.5". Now, that being said, does EVERY vehicle have too much weight on the rear axle when towing? or are they designed differently maybe such that a vehicle can be designed to not have too much sag with a full tongue load? (ya know, like in the case of a vehicle where they designed it to be used without a WDH ;))
No, not every vehicle that squats in the back when loaded is overloaded. Many newer trucks will squat the first few inches with relatively light loads because of multi-stage springs. The first stage of springs is fairly soft so that the truck will ride better when unloaded. Add some weight and the truck squats to the next stage of springs that are stiffer in order to carry a load.
I phrased it poorly, but that's exactly what I was asking. If vehicles sagged even when they weren't overloaded and as such needed WDH. And the rest of my question was about the design differences in vehicles designed to not take a WDH. And it would seem like the designs are different as my vehicle only drops up to 1.5" after a full tongue load. There isn't "a few inches" of drop ever unless you've overloaded the tongue.
