I really dislike air bags...
1. Air bag fails your trip is over. And it could be just one bag.
2. Off road performance. You are basically ridding on a bouncy ball. Which is fine on road or extremely light off road. But try taking whooped roads or pot holes or rough terrain. It is not a desirable suspension system and quality shocks won't help.
I think air bags sort of make sense for trailer towing... since you'll be driving slowly anyhow. And you have the soft ride when disconnected. I still wouldn't choose them. I've been running the Timbren bump stops and fully stock suspension on the F250 (shocks have been on back order and springs just completed). I think it's an excellent air bag alternative that is cheaper, simple and reliable. Can't wait to get the Fox shocks and Deaver spring installed!
Of course, the issue with building your suspension around the loaded hauling weight is the ride may be a bit rougher if/when unloaded. But what I've found... Quality Deaver springs built for max weight with quality tuned adjustable shocks will ride better than the stock oem truck springs/shocks. So if you can live with the stock ride... anything will be an improvement!
The HUGE upside of building suspension around your loaded weight is that it handles AWESOME! It feels much more nimble almost like a stock truck while fully loaded. You can hit the big bumps and fully absorbs them. And you have reliability, simplicity. Which in the end is most important to me.
We've taken the F250 out already and caught some air on whooped out sections of road. It is incredible how it handles - not harsh or bottoming out. My old 2016 Tundra with Four Wheel Camper could catch air and enjoy a pillow landing. It was fun in Baja driving 60mph on rough roads.
So in the end... depends on what you want and how you plan to use it.
Where do you get your information from? Air bags are not like riding on a "bouncy ball" in any way shape or form.
I drive on nasty whooped roads and rough terrain daily with air bags, no difference from stock when unloaded.
Also, airbags are better off road than timbrens. (though neither are great) Timbrens limit suspension travel and make it very difficult to retain stock or stock like compression. Airbags with a proper daystar cradle allow full droop and within a few mm of full compression.
A deaver leaf pack is great when loaded, and would be my choice 100% of the time for a full time rig, but again, makes the ride very uncomfortable when empty. All shocks do is control the springs, they do not make it ride any better in any way shape or form. They control the springs and keep the truck from bouncing.
