Don't own one...but have been in both NL and BF...and while there is something to be said for the glass construction (for the most part NL do seem to be lighter than BF)...they both feel....dark?...cave like?
They don't have a lot of windows, kind of like a cocoon.
Some Folks might like that, and it may be a big plus in cold weather.
We like our Adventurer, it is bright/airy, nice views out the generous windows, and it has proven to be rugged and well made.
You really need to spend some time in different ones and check out floor plans...they all have a unique "feel".
I do like NL...and would strongly consider buying one...but our next TC will likely be a single slide.
