the airbags help with keeping the rear of your tug semi level however, its not a good idea to use them to support your rear end.....
I run mine(Patrol at about 10psi & Cruiser 8psi) they are to "help" dampen the downward force of the van being attached.
if your rear end is drooping too much with the van attached - new Suspension is required
if its drooping slightly, with the van attached - airbags will help
there is several pic's of mine here

also, the old adage of where you load your center of gravity & where on the chassis you have things - in the center over the axles - best place
my $0.05 worth........
cheers
