Air bags

I have used air bags on my last three trucks Including the one in the sig. First I use Air Lift Ultimate. They can be run without air as they have a bumper within them. The first truck I always had to make sure I had 5lbs in each min. when empty. I use them to assisted with the loaded ride. They make a difference on bad roads. They will level out truck aka headlights Also I put a compressor on this truck what a nice option. My opinion is I tow big, heavy and far. Why not make the journey as pleasant as possible.
