Extreme weather package???
Looking at some Salem Hemisphere travel trailers and wondering what the difference is between aan extreme weather package and heated under belly. I can't find any descriptions.

You will have to find out from the manufacturer, because these descriptive terms and option names mean different things to different manufacturers. At the minimum I would want it to mean dual-pane windows, air-locking of vents, walls at least an inch and a half thick, and an actual basement space. An option so named, however usually doesn't have this much, because it would require a different basic construction than used for light weight, and would more likely be a different model line.
