Congrats on entering the World of Hybrids!
hybrids are a great RV to share with families, especially kids.
i will tell you that the "top of the line" comment is not true. if it was, there would be lot more of North Trail hybrids on the road.
in the 8 years i've been on numerous Hybrid forums, i've only seen a couple of North Trail hybrid owners on them.
i would say that they are nicely built but no better than a number of other brands that sell way better.
and NO hybrid is "especially" built for colder weather. the only thing that hybrids have as an option, is heated holding tanks and dual pane windows.
if you've got big holes with tent ends in them, there's no such thing as being built for colder weather.
if you want to camp in colder weather, there are a number of mods that we hybrid owners swear by.
one is getting a set of Popup Gizmos for the tent ends. these help with temp regulation, condensation and protecting the canvas.
second is putting Reflectix in the tent end windows. or you can get PUGs' Solar Liners for each end.
