Airbags are not for offroad use. They defeat the purpose of a well-sprung 4x4. That being said, it may be a non-issue for you, especially if you stay on FS roads.
Otherwise, you're going to have a lot of fun.
I'd recommend that anyone with airbags who does a little off-roading consider adding a set of Daystar cradles. It releases the bottom of the airbag from being permanently attached and allows for greater articulation. I have not had any issues off-roading whatsoever with my airbags and Daystar cradle combination. I have A full Dakar leaf pack (plus an extra leaf) and normally don;'t inflate my airbags over 20psi.
