The thread you cloned this one from
Message-ID: in alt.survival
was about "camp" trailers used by sheep herders. Look at some the data
sheets on them. The windows are designed for emergency exit.

what to do in case of fire.

Best solution - don't have one.

External furnace. Isolated hot water or air into the trailer via
piping designed to be disconnect and reconnected easily.

Internal. Several layers of heat shields with natural or forced air
flow between them. As long as the outer shield can't get hot enough to
combust what's around it, you are good to go. Gets every bit of heat
out of the fuel too.
