What I have found works best is what happiest said pretty much as well. What I do is measure the front wheel well to the ground. Then I hook up to the ball and leave the vehicle off for a bit. With the vehicle off I attach the spring bars, then start the truck and let it do its thing. Remeasure the front and make sure its within 1/2 inch of unloaded.
I have yet to find a definitive answer on exactly what to do. I've tried multiple different ways, this one seems to work the best.
Mine says this in the manual:
If a weight-distributing hitch is being used, it is
recommended to allow the shocks to inflate,
thereby leveling the vehicle prior to adjusting
the hitch.
But the idea of that is somewhat short sighted. Right now my truck is off in the parking lot. The shocks are inflated. Will they inflate more when I start it? I don't know. The truck runs a quick check when its started of the system, in which the compressor runs. But it can also open a valve to let some pressure out. So how does it work exactly? I have yet to really figure it out.
Does GM mean that my truck should be running and then I should adjust? Or does it mean that you should let the shocks inflate, shut it off, load on the trailer and then adjust?
There are many different angles to look at it. I've yet to find a specific answer. My truck is a 2007 tahoe with the autoride suspension.
