Another thing to consider is we're IFS, not Solid axle. We have to drive the truck with the front. We are more stable on a side hill compared to solid axles. Are front A-arms are what hold use on angles, along with how tall your rear bumpstop is.
My truck will hold at a 42 o angle. I'm also using airshocks in the rear. When on the trail the air flows between the shocks. That way it is always trying to give 50/50 pressure. When one tire is stuffed the air pushes the other tire down. Even with this set-up it is vary stable.
When it's time to get on the highway I seperate the airshocks. So on road they work like a sway bar.
