Opinions on air bags for 2015 HD 3500 to carry my Lance 855s

Without air bags, I do not see how you can eliminate rear sag. The truck must squat for any springs to engage. You can reduce the sag with springs and related, but not eliminate it.

I disagree with the top heavy nature of a TC will cause sway if you are off your overload springs. If improperly inflated the bags might increase sway, but that is the purpose on an anti-sway bar. I base this on personal experience. My 2WD 2500 Dodge has no overload springs, has an anti-sway bar, 19.5 tires and my TC weights 4,200 lbs.
