No question air ride has its place. I have it on my Tourliner. 6 bags 2 compressors and 5 gallon tank and it is 10K lbs. Been trouble free for years. My Cgt is coilovers. Its 4" static off the ground and built to go around corners.

Both have their merits. I tend to lean more to the coilovers as it is usually cheaper and less complicated. But it depends on the build.
