Dual cam VS Equalizer...I have both

No. The trailer will want to return to center because of the cams! Think of it as trying to pull a log out of a ditch as opposed to dragging one across the flat ground. Let go of the log in the ditch half way up and it will go back to the bottom. Same theory goes to the dual cam. Now stop dragging the log on the ground at will stay where it stops (friction sway bar/EQ). Very simple physics really!

Your rolling log analogy doesn't apply to the dual cam because the "cam" does not roll.
The cam simply is a rounded surface which slides along the bar slope.

If the cam is moving away from center, the friction force increases.
If the cam is moving toward center, the friction force decreases.
