Northwood Arctic Fox. ...but then I'm biased

Like you, I spent a fair amount of time researching. For me, a strong suspension and higher quality insulation were factors. I chose a 2012 Arctic Fox 22G. Picking it up next week. They are heavier trailers, though.
Good luck with your search. My opinion - do your research and gather as much information from folks who aren't selling anything as you can. I found the folks here to be of great help!!
