factory suspension bags?

[Bob Gervais]

I'm looking into those myself, it seems that Firestone is the most popular brand. From the research I've done, those bags are rated at 5k lbs. of extra load capacity ( along with the warning to not overload your truck, lol ) and have a 100 psi maximum pressure. The lowest price I've found so far is around $200. I'm really more interested in keeping the truck level when I tow the car trailer. I know the truck can handle it, but the lift springs I put in the rear are softer than stock. It'd be nice to hook up the trailer and not have the nose high.
