Cannot comment on how the suspension will stand up to corrugations but I have installed "in spring" air bags to cater for excessive ball weight when towing my 2.5 tonne caravan. Got them from truck Springs in USA at half the price (posted) that they wanted for them here. I only need to use about 10 PSI when towing and they advise to keep at least 5 PSI at all other times. Can still use all the height controls and suspension options. Happ to answer any other questions.
I was told I had to change the rear springs for more solid ones as the airbags would herniate out the sides and puncture. Interested in any information you have after your installation. Sounds a lot cheaper than having to replace the springs.
