I tend to over research almost any purchase. TV, surround sound receiver, PC, camera, ect...I read specs and reviews then narrow down to 2 and decide. Of course cost to features is a concern.
After reading posts and viewing the "Show off your 2015+ leveled Tahoes and Yukons!", I took into account ride height/stance unloaded and ride height/stance loaded with trailer/ gear. Traditional rear struts vs. auto-level rear struts, I "think" I have it narrowed down to a 2.5 inch above strut level
My Suburban has auto-level air shock in the rear, they keep the rear at a static height. I think mine sits pretty low in the front.
I used some painters tape to the door ding body line.
