Let's talk air bags...
My 1999 7.3 dually has airbags installed by the previous owner. I've generally not bothered to inflate them unless towing a trailer with my Bigfoot camper (4000lbs loaded). Today while driving on Cali...

I had Timbrens on my 1500 back when it was stock and they sucked empty. I had very little travel before engaging them and when you did your spring rate seemed like it hit infinity.
Better suited for heavy loads than lighter loads for sure. They are somewhat height adjustable so you can balance when they engage with how much sag you're willing to accept.
Wouldn't recommend them for "a little" support and if only used occasionally, keep them short so you get enough travel for empty truck bed under normal road conditions and they only engage under a decent load.
I ran 'em for years on a few different half tons. But they were work trucks that the company felt I only needed a 1/2 ton.
After a 90 gal slip tank and hundreds of lbs of tools in the bed all the time, you almost couldn't haul a trailer with any real tongue weight, without some extra rear suspension. Mine basically rode on the Timbrens 24/7.
No, I didn't care about payload rating. Would also run the first set of P or XL tires up to 60-65psi in the rear to get the squish out of the tires.
FWIW, a 44psi max rated tire will run all day long at 60psi with more weight in the bed than should be there, without issue!
