Keystone / Courgar "Polar Package" Experiences???

I just bought a new 2016 Keystone Couger X-lite 21 RBS with a polar package. I am a bit skeptical about the polar package also, but I live in Georgia so I’m not to worried. Although I plan to visit family in the northern states in the fall time frame. Also I did notice that when I cut the access flap in the plastic material on the bottom for the slide motor I noticed the water lines were bare. I might put some insulation on them if I do go to colder climates.
