We are continuing to fine-tune our cold weather camping routines -- and we noticed during our last very cold trip that water would sometimes drip from the air conditioner vent. Very refreshing to have a drop of 33 degree water on one's neck in a 34 degree trailer!
I am pretty sure that this is condensation from humidity in the air inside the trailer that froze to the a/c machinery during the night and then melted when we ran the heater in the morning.
So that is my question -- would covering the air conditioner shroud, up on the roof, prevent this from happening? Once in a while, we see an RV with a tarp wrapped around the a/c during the winter -- what, exactly, is the reason for wrapping the shroud? (Frankly, I would rather not wrap the shroud -- it is not easy to climb up onto the roof of my trailer at home, and the tarp could flap around and damage things. I would secure it well, but there is always a chance that it could get loose.)
A related question -- does air flow through the a/c when it is not on? On one hand, that would not be a good thing, since it would just make the trailer colder. On the other hand, fresh air circulation is a good thing. On the third hand, I can get all the fresh air we need by simply opening the hatch in the bathroom a little wider.
(Finally, a note to the moderator -- I posted this on the boondocking forum, on the theory that boondockers have a lot of experience in dealing with very cold weather camping. This is not exactly a DIY issue, nor tech, nor exclusively a trailer issue. If it is in the wrong place, please feel free to move it.)
