Don't put too much emphasis on the "off road capability" of this unit. At that size, weight, and clearance, it won't be doing any off roading beyond the basic forest service roads shown in the videos. And that's likely perfectly fine for 99% of people (me included).
The interior layout looks nice. I don't like the windows they are using - I had the same ones on my last trailer and they 1) condensate a lot, 2) have poor lock-out and latching methods. I mean, they work, but they could be much better.
If you want a
truly winter capable setup, you should look into Total Composites:
Travel Trailers - Total Composites - https://totalcomposites.com/travel-trailers/. But their products come empty and require a full interior build out.
