Mine has almost every add on you can do to an F53. I have never driven a DP,with air suspension but the ride of mine is amazing. It floats down the road. The previous owner also replaced he shocks with Konis IIRC. The only time you feel anything is very bad bridge expansion joints. And even with that it's not bad. What air pressures are you running? The Sumos should make it a smooth ride.
