Class A's in the 30' range off the top of my head - in no particular order:
Thor ACE, Thor Hurricane, Winnie, Vista, Winnie Brave, Newmar Bay star, Newmar Bay Star sport, Forest River FR3, Forest river Georgetown, Tiffin Allegro Breeze (DP), Tiffin Allegro 31SA, Coachmen Pursuit, Coachmen Mirada, Fleetwood Southwind, Fleetwood Bounder... I may have missed a few but you get the idea. PLENTY of options in the 30' range.
One thing is certain, you ask for folks on here to tell you the best quality brand - 99% of the time the advice will be what they own. Even if their experience is based on a model or year nowhere close to what you are looking for.
