Welcome to the forum. I'll see if I can answer some questions regarding sway which seems to be your major concern. Blue Ox makes 3 different weight distribution hitches. Don't use the round bar hitch with chains as it will do nothing for sway. The concept behind the TrackPro WDH is obvious as it is similar to Equalizer and some Reese products. I don't see the physics behind the SwayPro WDH except it relies on shorter chains and maybe a wider set on the bar mounts. It wouldn't be my first choice.
Your Escalade may be exacerbating your problem as I am assuming you have automatic load leveling. When you put a thousand pounds on your hitch ball the vehicle will pump up its air bags and level the load automatically. This is bad. High bag pressure on your rear axle will harden the suspension and cause it to serve as a fulcrum. The hitch weight will then unload your front tires and make things squirrelly. See if you can defeat this feature and rely on your weight distribution hitch to level the rig with trailer attached.
Thirdly, see if you can cancel your Blue Ox order and put the money towards a Hensley Arrow or ProPride hitch. Either of these will eliminate sway which is your concern. Good luck and enjoy your trailer.
