Ikon is a nice unit, but don’t have experience with a recent model year.
Generally the Ikon, being a super c, will be noisier, have more road vibration but also have a better feel of the road than a typical class A.
I don’t know what mods Renegade makes to the chassis in recent Ikon builds, beyond the traditional frame extension. Our 2014 has a Cummins ISX15, which isn’t known to be a quiet purring sound.
Newer models with the DD engines, even at idle, are much quieter.
The biggest gripe I have read from those not happy is that the front axle is spring, not air. You will feel bridge transitions and rough road.
Solidly built unit and appreciate the factory support - we stop by every year for any tweaks or items I don’t or cannot do myself.
If the ride luxury softness is your biggest concern, I would not get a super c.
