Before I got my Phaeton I owned a 2012 Breeze 28BR (from new) and put about 35,000 miles on it in two years, including one trip to the Canadian Rockies. It was an enjoyable coach for me (my first motorhome) and was generally trouble-free. I believe the Maxxforce engine issues started with the 2013 models, when an exhaust brake was added and emissions settings changed, as I had no problems with mine. I flat-towed a 2dr Wrangler.
While my Phaeton is very nice, there are times when I miss the better maneuverability I had with the Breeze.
