Good looking truck. I just picked myself up a 2015 1500 High Country as well. How well do the 33/12.5s fit with the 2.5 level kit? Any rubbing? Any issues using those stock rims? I had 305/55/R20s on my Tahoe that I just traded in and had some trimming to do with the Rancho quicklift installed. I was initially thinking of just going with a 33x11.5-ish tire with the stock wheels. Any issues with pinion angle or steering geometry with the leveling kit?
