My dealer dont know how to set up a wdh either. In fact they got it wrong with both times they tried. Now I do that myself thank you.
What i did was get 3 weigh ins at the cat-scales.
Truck & TT w/o wdh bars on
Truck & TT with wdh bars on
Truck all by itself.Now you can crunch numbers.
With that info you can see just how much weight your shoving forward back to the front axles.
Now I know GM per my owners manual," says get the front back to but not to exceed going lower then stock height in the front".
Here is a link from the FRF library going into the details http://www.forestriverforums.com/for...do=file&id=128
