I know it's been a while since I've responded here but I have additional information.
I went to the professionals in Eugene and he suggested that all I need to do was change the angle of the head on the hitch. I did that and it took out most if not all of the sag. By tilting the ball a little farther out from the truck it forced the bars, still dropping 2 links, to take up more weight transfer.
I've also got weights, loaded and unloaded.
Unloaded no trailer: Truck front axle 3250
rear axle 2450
total 5700
Truck and trailer loaded: truck front axle 3300
truck rear axle 4150
trailer 6450
total 13900
If you take the unloaded truck weight only and subtract it from the total truck and trailer weight you have a loaded trailer weight of 8200. There was probably around 200 extra lbs in the truck when loaded.
Two adults were in truck at each weighing.
Okay number crunchers chew that up for a while and see what we get....
Oh, one more question: When considering "tongue weight" is that with WD bars connected or disconnected?
