Default Offroading, crawling, articulation and such

Hey all,
I'm newer to any offroading but am just getting in to a bit of it since I moved to CO. I was doing some the other day, and I was on a very off camber straightaway and got out and looked and my downhill suspension was fully compressed and my uphill was fully extended, which served to further lean the body of the truck even more off camber than the hill itself. Which doesn't feel nice.

So, without flaming me for not knowing, explain to me why this is. I would have assumed the suspension would do the opposite and the uphill would compress so the body would lean less steep than the camber.
Is this a function of the sway bars? My understanding of the sway bars is that if one side compresses it will assist to suck down the other side too, so I'm not sure that has any effect on this.

One other thought: I have the air lift coil spring inserts for heavy towing installed and at the lowest allowable pressure, however they are connected right and left on a common air tube, so I'm wondering if compressing the downhill one would then in turn increase the pressure on the uphill therefore causing it to extend more? I'm thinking to try this again but open the air port on the air lift to see if any change.
Thanks for any knowledge you can throw my way.

I recreated the scene at home, here are pics.

Not familiar with this but it seems like basic weight transfer would do this at least to some degree. I'm anxious to see what more experienced people will say.

I'm no off-road expert but I'd guess that since the front of the truck is much heavier than the rear it has more of a say as to what angle the truck is going to follow. Rob

Looks like normal articulation out of a truck with IFS to me.

Interesting, since the Gen 4 RAM is not an IFS truck...

NM. Thought they were referring to something else.
