My previous vehicle was a 120 Prado, and before that a Kia
Sorrento. I used airbags in both of those with great success and with that in mind agree with HKB's general premise. There is good effect with airbags in coil-sprung rear ends and very few issues.
However with leaf sprung rear ends, especially twin cab utes, you have to be really careful and I think that needs to be made clear to Boris.
You can be loaded to near GVM, perhaps with a bias to the rear as so often happens with touring, but NOT overloaded, and with inadequate springs you can end up in trouble with airbags if they are used to lift a saggy bum.
As you said, HKB, " it shouldn't take too much pressure to get the vehicle to its normal non loaded height." That's the key point. **
The springs have to be able to do the great bulk of the work.** If
the springs are right then low pressure helper airbags should be ok. But I'd still be careful.
Not having a go at you , HKB or being critical. I just think that the difference between airbags in coils and airbags in leaf-sprung rear ends needs to be emphasised
Personally I prefer not to use airbags at all. In my twin cab BT50 I have spring packs that do the job without air bag assistance. A bit hard around town but comfortable and capable when loaded for touring, which is what I bought the vehicle for.
