When I was researching lifting/leveling my 2022 3500, I noticed the biggest difference between Levelling and lifting is Leveling there is no frame mods required. Lifting you generally have to cut your frame cross member and bolt a new one in. This deffinately voids warranty of the truck. With Leveling, my dealer installed the kit I picked (Suspension Maxx Stage 3 leveling kit and a 2" block in the back), and they still are warranting the truck. The setup is also able to run 37's with some minor trimming. 35's all day would fit with this setup without the mods.
Note: if you are doing either of these, you need to add a couple of extra kits to your list to improve ride performance. Cognito PISK kit, and a steering stabilizer kit. Helps with reducing the wandering in the lane while driving problem a lot.
