Air bags on the rear suspension?

[Factory Guy]

Since Many Semi's have logged millions of miles with airbags on their trucks has anybody (i did a quick search on this for this on this forum), added these to improve their ride in the rear of the truck? I have ZERO interest in "laying frame", on this truck or even "C" notching the frame in the rear.

Basically here's what I have, a 1973 GMC Camper Special 3/4 ton (2wd), and I would like to improve the ride (especially in the rear). Since I have no plans to ever load this truck down again with a Camper and a Boat, I am thinking of placing some heavy duty air bags back there to improve the ride, yet also have the ability to carry a heavy load if needed.

Since I have gotten this truck (some 4 years ago), it has seen ZERO heavy load carrying. So going forward it will be mostly pleasure ride.

Thoughts?
