If you sleep in a camper, or in the nose of a
gooseneck trailer, also consider if the cold is coming up from below you. Make
sure you have insulation, or even a tarp under your bed. Not all campers and LQ
trailers have been insulated the same, and I found that I was feeling the cold
from below me. Kind of like the days of tent camping and putting a barrier down
on the ground under your bedding.
