so everyone recommended new springs since shocks don't hold any weight, so you got new shocks

air bags DO NOT add any capacity. They are for load leveling and ride control only. They make no claims to increase payload.

That's were you are wrong. Air bags depending on the style will increased load. I had inner spring bags and they increased the capacity by 1000 lbs. As stated by the bag manufacture. And would raise the truck bed depending on air volume 3 to 4 inches.

You can put springs off of a diesel locomotive on your half ton and it is still a half ton. If springs have gotten weak, replace them; if you don't have enough truck, get another. I don't like air shocks, they are designed to make money for the manufacturer. Having an opinion doesn't make you right.... same for me, its just my opinion... although, I am seldom wrong

That's usually the way it goes on a forum.
Subject has a problem, with a solution he likes... Asks for opinions... Does what what he was going to do originally.

Your wrong, adding extra leafs or air bags do NOT increase your vehicles weight rating or cargo carrying capacity.
Period.

normal for this form people think that they know everything about every product on the market and they know little. If you install a coil spring air bag and when inflated it dose not allow the spring to compress as much as before then the spring is getting a greater pay load from the bag. That is not saying you have made your 1500 into a 2500 truck yes you are right as it improves handling by increasing the payload of the springs. How else do you think they work. As for the original question the person had an older truck that he was not able to get a new one at this time and he was looking for an economical way to get a better ride and raise the rear of the truck during tow until he can afford a new truck. Just because he went with his original idea dose not make it the wrong idea for his needs.

Problem; sagging weak springs
Solution; adjustable shocks?
He in fact wasted money .
I'm not sure it's even a band aid.

One of the issues that people forget is legality.
If you bugger your suspension in an attempt to carry more weight, you don't/can't change the GVWR. The GVWR can only be changed by the manufacturer or a qualified rebuilder.
If you then try to carry more weight than the GVWR allows and get into an accident, and if the cop questions it, you'll be in a legal mess.

IMO, that's fear mongering BS. Cite some specific cases that you know of and what state and the circumstances.

I stand corrected. It's not legal for a business to modify the GVWR unless they are qualified. Quote from the NHTSA legal counsel is below. Notice the last line.
“Because we do not regulate how individuals modify their own vehicles (and thus do not prohibit you from modifying your vehicle’s suspension), we are unable to advise you about the specific modifications that must be made to a vehicle for it to safely carry an additional 1,000 pounds. Among other things, however, you should carefully evaluate whether the vehicle’s axles, brakes, tires, and frame can adequately handle the additional load. We suggest you consult with the original vehicle manufacturer about this question. You may also wish to consult a local attorney concerning possible liability in the event your vehicle is involved in an accident.”

That's just NHTSA covering their own a--! Typical of every govt entity or any business.

Connecticut state law Section 14-167a: "The axle weight on any axle and the gross weight of any vehicle or combination of vehicle and trailer or vehicle and semitrailer or any other object, including its load, may not exceed the manufacturer's axle weight rating, the gross vehicle weight rating ...."

Before this turns into WW-3 , about axle weight and the law of it, the OP asked about shocks and spring replacement, he went his route with shocks ( in my opinion wrong route) end of argument , lets talk of better things , don't need to put beer in fridge now its getting colder outside. .

Isn't it amazing how when the OP decides what to do, right or wrong (according to experts), the thread drags on and usually ends in meaningless rambling. This is typical of all threads and is worse when the subject is pulled towards truck brands or models, weights and capacities or tires; like they usually do. This thread isn't as bad as some, if it in fact it ends now.

Thanks for the comments. So far the rear shocks are great - lifting the rear end back to where it needs to be when hooked to our trailer. I don't plan on carrying additional weight, so that shouldn't be an issue. At least now, and thanks to all your comments, I know what my next options are.
