Help Deciphering CAT Scale Weights
Hi all, New to the forum, and to RVing. I want to make sure my WDH is adjusted properly. I took my rig and travel trailer (TT) to the scales this past weekend and did three passes: first was hooked...

As I think about the numbers some more, things don't add up to me. When using the weights in my original post to calculate tongue weight, I get 940 lbs. However, looking at the drive axle weight on Pass 2 (connected to trailer, no WDH bars), the change in axle weight is 1,400 lbs. from the unloaded weight (Pass 3). If tongue weight is 940, how is the axle weight increasing by 1,400 lbs. when hitched to the trailer without WDH bars? I might need a physics refresher to set me straight.
That increase is because the weight is being removed from the front axle when you put the trailer tongue on the ball. You get the weight of the tongue PLUS the weight from the front axle that was teeter-totter removed. Thus the scale shows the tongue weight plus the removed front axle weight. It is the goal of the weight distributing hitch to place all or most of that weight back on the front axle. In other words, your truck front axle should weigh the same AFTER hooking up the WD bars as it did solo BEFORE you hooked up the trailer.
In your particular case, I would try to adjust the hitch or take up some more on the WD spring bars to transfer some more weight forward.
