No, the headliner does not get wet. Yes, we still leave a couple of windows
cracked open slightly to prevent excess humidity and stale air with four people breathing in a tiny 10’ cabin. Yes, we can still get some condensation on windows
. No, it’s not enough to wet the walls, cushions, or bedding.

on a low setting throughout the night.
We have a Scamp
with fuzzy marine headliner over foil bubble wrap.
