Everybody has different reasons for liking or disliking airbags. I not only feel that the ride is better with them, but I also enjoy the ability to adjust ride height and quality. My truck handles the >3100 lb pin weight without the bags,but it just rides better with them.
I already had the airbags when I recently decided to install a 2" leveling kit on my truck. I hate the down hill look that an F350 has when empty. I was concerned how that was going to work out with the toy hauler, but adding another 8-10 psi to the airbags keeps it fairly level and unbelievably provides a better ride.
