Air shocks are really not meant to hold the entire truck's weight, but that doesn't mean you can't use them that way. Wouldn't recommend it as it wouldn't last as long as you'd like it to last.
If you go with cylinders, the common cylinders used in cars now is not enough for a truck. You need a larger diameter cylinder to hold a truck's weight. You can use the smaller diameter 3-4inch cylinders, but you'll be pushing 150+ psi into those things. Minimum should be atleast a 5inch diameter cylinder, which is the diameter of a small sized bag like the Slam 52's
