NEVER use a portable propane heater inside a trailer! Portable propane heaters are NOT designed for use in such a confined space, and the threat of co poisoning or even death is very real.
Why not use the trailers heater? It is vented outside and the fan runs on 12 volts.

I would trust a 30 year old furnace before using a portable propane unit!
Test the furnace, make sure it functions correctly. Far safer them portable gas heater.
