Leafs to Coilover

I’ve finished demoing my sprinter and have been driving it around. I noticed the leaf springs give it a pretty bouncy ride and was wondering if anyone has ever attempted a coilover on a sprinter or living van and what benefits they saw. I would think things would rarely vibrate apart and the ride would obviously be smoother.

Or have you noticed that once the build is done that the weight keeps the ride smooth with leaf springs? Very curious thanks.
