inmydreams: I might interject, because of your interest in the Wolfcreek and someone's mention of a Northstar.
I chose quite a different route, that of restoring a vintage camper. But I was looking very hard at a new and researched very hard for the best for me. I wanted small as possible and no slides. I concluded either a Northstar or Wolfcreek.
I hope you'll take the offer to view the Northstar up the road. I also hope you'll see a Wolfcreek up close and personal before your final choice and purchase. I also agree fully with the used unit purchase idea to save money, but if memory serves me, the 850 is the new floor plan and if so, it was HIGHLY desirable to me over the 840, so you may not find a used one.
Don't be overly concerned with the step-up nature of the bathroom. As it turns out, that's how I'm dealing with the compromise of a bathroom in a small (shorter) camper.
Good luck!
