I went through this same decision making process last year. See my thread
here.
Bottom line is that I ended up with a Northstar 850SC popup. Weight, clearance/drivability and storage options were all concerns that I was able to address with a popup. After one season, I couldn't be happier with my choice. I sat through the whole winter wishing I was camping again and am anxious to get the season started.
One thing I would say is that unless you buy new, you will have to adjust your needs slightly based on what comes up on the used market. I would have purchased an Outfitter, Hallmark or Northstar and when a nice clean one came up for sale, I had to move quickly!
Good luck on your search,
Mike
