"Extreme weather package" means there's a covering over the bottom of the RV with possibly a layer of the chrome bubble wrap above it, basically a catchy advertising gimmick along with "polar package", "artic", "4seasons", "half ton towable", "solar ready", "dry weight", & "max tow weight".
Your furnace has a small duct outlet pushing a small about of heat into that underbelly to aid in freeze prevention, so you can use it in cold temperatures even below freezing, but without other means of keeping lines & tanks warm.
