The owner of KZ sold out to Thor Industries earlier this year due to his age and health. No outward signs of any changes that I know of. I have my suspicions but will have to wait and see. We have one of the last non-Thor units. Our dealer expects to see a move towards more bling and little features, sorta like on Keystone units. We love our 2014 Spree.
KZ has been pretty good to us. Our dealer has been outstanding, the opposite of a previous dealer (Coachmen). Zero issues on getting any warranty problems fixed. Just a few minor warranty issues so far to deal with our 2014 except for the bathroom wall which is out of plumb.
