Danged... If I could only think of a way to get the trailer in the yurt... Where's John in Kansas???...
Hey, how about clear plastic, like half a tent, from the roof to the ground on the south side of the trailer to act as a solar collector??? Yeah, yea might have to get a piece large enough to go over the entire trailer but if you could corral some solar that might help...
23 degrees inside is dangerously cold to be living in... I mean, eskimos do better in igloos...
