I just ordered the 12K Equal-I-Zer hitch so I can install it for the long haul to Ohio for the BPG and GSX Reunion. It should arrive MOnday so I can install and prepare for the trip. I bought it from Here I have a 2003 Escalade ESV with factory tow package and self leveling system. It pumps up to level when first connected but will "squat" 2-3" after driving down the road. Hoping this is the solution for safe hauling since I'll have the whole family with me.
