Welcome to the forums, and good luck with your search.
I don't have a recommendation for a specific camper, but since you are in the market, I'd like to give you at least 1 more item you need to consider, new or used, and that is the slides.
You said slides are a "must". Slides are nice and do provide extra room when extracted. BUT you also need to consider the functionality of the camper when the slides are IN also.
With slides IN is everything inside the camper still functional? Can you reach the bathroom, can you access the refrigerator, can you still use the sink, and the stove. Can you reach, open, and use the drawers and the cabinets?
You will find yourself using the camper with slides IN sometimes. I think, probably, everyone one on RV.net has used their camper some time or another with the slides IN, on the road, in bad weather, or at home if you have a restricted parking space that won't allow slides out.
This will probably limit your search even more. I looked for 8 years for the right one before settling on a camper with slides. Then it was a new one. But it is 100% accessible and usable with the slides in. Keep searching, you'll find the one you're seeking.
