I recently disassembled the furnace in my travel trailer to lubricate the motor. While re-installing the unit I wondered if it would be more efficient if I insulated the heat chamber. Any opinions about this?
No.
It would be come a fire hazard :E
The entire furnace is COOLED via the air moving all around the furnace housing. Covering the furnace housing with anything will most likely cause the furnace to overheat and IF you are "lucky" the over temp sensor "might" shut off the burner before it burns down your RV..
Do you feel lucky?
If you are trying to squeeze more efficiency then you need to forget about RV furnaces, just not happening. RV furnaces just are not designed for high efficiency in converting the propane heat to hot air. No, instead they are designed to get the max heat possible in the SMALLEST foot print..
