Martin, I have used Airlift bags on the rear of two different Rangers for a total time of around 25 years. They are great for towing and Overlanding. Air does need to be in them at low pressure when not loaded because they can collapse and the folding can cause damage to the bag. This is not a big problem but the pressure should be checked occasionally. They do need to be replace periodically but last a pretty long time and they are not that expensive.
They really stabilize the rear of the vehicle as well as eliminate excessive sag in the rear. I highly recommend them over any other means of stiffening the rear. I have tried Add-a-Leaf springs and that makes the ride terrible when not loaded and does not stop sag when loaded heavily. I know you have coil springs but AOLs would be the equivalent of installing stiffer coils.
