In 2016, there was some discussion that the Whisper Quiet was not very quiet. It seemed as though the ACs were producing a good volume of air, but some folks experienced that the duct work design was not getting the air volume into the room. Heartland was using a laminated roof structure which has foam "channels" for the ductwork. Some folks have created dams and such to help direct the air to the vents better. Not every rig or every floor plan suffers, it's just we had a handful discussing it as an issue here on the forum.
In 2018 models being released now, they have changed the roofing structure to joists and bat insulation. I am not sure how the ductwork is constructed, but pictures show more vents in each area of the coach.
Also, I have not heard of any front cap fading since Heartland changed to the fully-painted front cap. The grey gel coat that was used back in 2011 or so was an issue and did fade. Heartland did help some folks with their fade issues early on.
