If you need air bags, or any supplemental suspension aids, then you really need more truck. Truck suspensions are designed to safely handle a specified load. Going beyond that and adding band aids is penny wise and pound foolish.
I will give you a perfectly good reason to use a supplemental suspension aid (for me Firestone airbags) that's got nothing to do with needing more truck.
You will see in my signature I have a F350 Dually pulling a 40ft fiver with depending on how I load it a pin weight of 3K lbs which is well within the capacities of the truck I think you will agree.
In fact with my trailer on the back before I installed airbags the rear suspension was not compressed by the trailer to where the factory overload perches engaged the secondary heavy duty spring.
Now this caused a very uncomfortable ride when traversing any significant bump or divot in the road when the suspension would compress a little further and the secondary heavy duty spring leaf would contact the spring perch with a "BANG" making for a very unpleasant towing experience. Installing the bag and inflating them to 40 PSI lift the back end of the truck back to the original ride height and the ride smoothed ride out by getting the extra sprint a couple inches away from it's perch.
BTW I ran separate air lines from my bags to valves on each side of my license plate making it very simply to add or remove air
