Some of your concerns I get ,the toilet leak ,no whisper A/C in the bedroom, sorry But it sounds like you just picked the wrong floorplan for your needs, Our 3735MK has MASSIVE storage and cupboard space and Pantry and as far as build Quality my 2015 is better in every way compared to my 2012 and that is saying a lot because my 2012 was a Great RV,WE took ALOT of time deciding on the floorplan that would fit our Fulltime needs and so far the last 7 months of ownership on our 2015 have been a great EXCEPT for the Stupid Toilt
and we are Happy campers,and by the way Redwood,Jayco and Open Range cheaply made?????? we looked at all them and I would not call them that IMO
