As bradyk says, look at payload first. The other numbers are interesting, and have varying degrees of applicability, but in almost every case, you will reach payload capacity before you reach any of the other numbers.
If your payload is truly 1530 and change,then if the calculations laid out like bradyk shows it are realistic, then you should be "ok". Depends on how much margin you feel you want.

Axle ratings are equally important. It isn't uncommon on half tons that a full payload in the back will put you over the RAWR.
