Winter camping with 2016 16TBS

[clvesier]

Newbie here

We are looking at a 2016 camplite 16tbs trailer made by livin' lite. Our options are limited to trailers with GVCR <= 5000

An internet article listed these trailers as 4 season.  From what I can tell, it has dual-panes windows but no underbody insulation/heating  of tanks or lines.  I believe we can install tank heaters/insulation to address this. Assuming we do this, does anyone have any insight/advice/experience about winter camping with this rig

Thanks

I also would like to know this answer. Did you come up with any solutions?
