If you are trading it in next year, then would it still be considered new for trade in purposes?
What's your budget on this? Or what price will you consider?
I can tell you that there are numerous used high end, better insulated (they really can only fit so much insulation in there)full timer-friendly fifth wheels out there that far exceed your Keystone product in build, fit and finish, room, etc. To name a few: Mobile Suites (any year), Dutchmen Grand Junction (2009, or better yet a 2010+ w/ Arctic pkg.), 2000+ Newmar "Aire" products (NOT Cypress or "Stars"),09+ KZ Escalade. There are more, that's just a short list. It has taken me quite a bit of time to compile data to create a list of older, better built RVs to choose from, primarily based on suitable insulation. That is what I suggest you and your wife do. Good luck to you.
