I voted No sway-bar because I plan on taking it off very soon. Maybe today.
I never thought of removing it, but it does make sense for us. I'll give a brief description of what a sway bar does by going into a bit of my BMW knowledge.
So, the sway bar connects your body to your suspension. The bigger, thicker bar you have, the more your body moves with the suspension and the less it moves to gravity (called body-roll). On a BMW a big sway bar is good. BMW's have big heavy bodies, but are the best cars when it comes to cornering, second only to a Porsche. The more body-roll you have the less cornering ability you have at high-speeds because the body of the car wants to keep going straight due to inertia. So the body physically "rolls" towards the outside of the corner.
Now, I ask you, how fast do you take corners in your fullsize chevy that only has a top speed of 85mph to begin with? We want articulation in our trucks and if your suspension is connected to the body, it limits that articulation. So, reasonably, as long as you don't take corners at high speeds you should be fine. You may feel your body moving a bit more than normal, which could take some getting used to. But your chances of rolling your truck haven't really increased very much.
Lesson over, now as homework everybody go home and take off your sway-bar!
