Yes, It would be a great add-on feature, Putting 4 small airbags like our pickups..But the dual axle setup on a trailer has alot of movement when making sharp turns or going over rough terrain..A stronger set up could be the addition of rubber stop bumpers in a shape of like a cone spring.. But when you look Under a 90,000$ 5th wheel weighting in at 16,000lbs and see a small set of leaf springs and then its attached to the frame by 2 welded tabs which do bend or break off as we have read on our forums here.. its time for builders to look into a more robust system
