The Yukon uses the same rear slide as the Everest. Host will probably offer the same things in this slide. Remember that Host is very customization friendly, so there are more options than listed on the website and on printed material. Your contact at Host will be Randall and it would benefit you to go through a factory tour and discuss how you would like your camper configured.
BTW: The Yukon bathroom is smaller than the Mammoth. It is the size of the Cascade you may have seen at the show. There is a smaller sink top and less room around the toilet.
