I've run 2wd offroad stock in the Sierra for about 5 years in this rig and got stuck twice. Recovery gear got me out the second time, I lacked that equipment the first time. I started pushing harder off road. A lift and rear locker, I won't say a types so I don't influence your decisions, helped a ton. That's my own personal expierence I encourage you to go have your own and mod based off those expierences.
Shhh my sig doesn't give you hints at all
