I'm looking at a 23 Yukon SLT with the 3.0 and max trailering package. I have a 18' aluminum car trailer that weighs in at 1.5k and I want to be able to load up a project car. Worst case I would hit 6.5K pounds. I have towed this same setup using my 2016 Colorado Diesel and a WDH with no problems. How do you guys think the Yukon would handle?
