I/we looked at the Fox Mountains. However they quit making the floor plan we wanted the previous year. We saw it at a show the 305 or 325. I felt the Fox Mountain was a better unit. It is not as glitzy as some of the other brands but felt the construction quality was as good if not better. Not as cheap $ as some of the other lighter weight brands (though it is not as lightweight as the Jayco HT's). Storage was better, it doesn't use a lippert frame, its gvwr was substantially higher allowing much more cargo weight in fact probably way more than you would actually use. It is certainly not a 1/2 ton towable unit but lighter than their Artic Fox line though I am not sure I would tow any of the supposed 1/2 ton towable units with a half ton truck
We ended up with an Eagle HT 27.5 rlts happy with it for the most part as well but have definitely had some issues with it we will see how it holds up over time.
Northwood has a very good reputation for quality at least in their Arctic fox, and Nash lines. The Fox Mountain line has only been out a few years(5 or so iirc) so there is no longevity reviews out there.
