Hi Gator -
Here is a video describing setting up a WD hitch correctly:
Setting up a WD hitch video
I towed a travel trailer with a Buick Roadmaster with rear air levelling suspension.
The manual stated to pull the fuse for the air compressor and set up the WD hitch without using the air levelling system on the rear axle.
So the information should hide somewhere in the owner manual for your Suburban.
An alternate method to get tongue weight is scale without the WD bars and uncouple the trailer on the scale, then subtract the trailer axle weight from the total uncoupled trailer weight.
You can also use a bathroom scale and a piece of lumber to form a beam.
Do this on a level concrete surface if possible. Rest one end on a block and the other on the scale so the beam is level. If you set the jack down exactly 1/2 way on the beam, the scale = 1/2 the tongue weight. If it is too heavy for the scale, move the non scale end closer to the jack and calculate the proportion. If the scale is 3/4 distance to the jack it is supporting 1/4 of the weight and so on.
