Both are well make and as stated prior both are heavy for their size relative to other RV manufacturers similar products. Spend some quality time on the Northwoods web pages and you can learn about the differences. Nash was typically wood framed (not that that is bad) while Arctic Fox was aluminum if that matters to you. Look at the width of walls, the front and rear end caps or not, etc. Then you can decide. I find the weight issue to be a minimal consideration between similar size units and would go with the Arctic Fox if you find a coach that works for you. I have a TT with a front end cap and it really is important to me not just for looks but for deflecting flying objects like rocks and blowing sand in windy areas. It is a well worth option for me. Another consideration would be to determine if you are planning to spend lots of the year in the RV, or just be recreational weekend RVers. The Arctic Fox is made well enough to support full time living in it. Not every RV you look at is designed for full time useage. I have been looking at Arctic Fox products as I would like a more full time living RV. I don't think you can go wrong with a Northwood's product.
