I've had two Northwoods Products. An Arctic Fox 19-B &, I purchased a 7 month old '98 Nash 25-S.
The 25-S has been in all the mountainous Western States, & back East to IN. , OH. , MI. , WV. , KY. & Ontario, CAN. , twice. The trips back east were all summer long & I lived in the trailer during those times. Three of my friends have Nash products, also, And we've all had very good luck, with them.
If I had to replace my trailer, I would buy a Nash/Arctic Fox product, again. They are not that expensive but, still provide good, solid quality.
BTW, I replaced a 1977, 25' Airstream with the AF 19-B. My experiences with the Airstream were different than those expressed in this thread. I've had all the inside doors literally fall off from a trip on a paved but, bumpy road. The doors were laying in the center aisle when I went inside the trailer. The "10 cent" hinges Airstream used were pure junk. The odd part was that the hinges on the entrance door were "enormous". If they had used some of the extra metal from the entrance door hinges to reinforce the inside door hinges, they would not have had a problem.
The gray water holding tank was only about 7 gallons. After my first shower, I was standing in water. Couldn't believe it!!! When I contacted an Airstream dealer, they said that trailer was supposed to be used in RV Parks, only!!! Just enough capacity to get you to the RV Park!!!
The top of the entrance door was so low that two of my friends cracked their heads on it causing one guys head to actually bleed. None of those guys were that tall, either. Needless to say, they HATED that trailer!!!! I'm only about 5'6". So, I never cracked my head.
However, the round, tubular shape of the Airstream takes a bit of getting used to. The only place where you have any height is if the center ailse of the trailer. The cabinets near the ceiling have very little storage due to the shape of the trailer. Sorta feels like you are living in a storm drain!!!
Most of the build quality of the Airstream is excellent, though. There is a lot of "over-kill" in this area. The furniture was of very good quality & very comfortable. The tow quality was exceptional, also.
Bottom line is that I would buy another Nash in a heartbeat!!! Much cheaper & much more liveable, in my opinion.
I don't mean to knock the Airstream product but, this has been my experience.
