I have a Chinese diesel heater inside my trailer. But I’m considering I using a Y pipe and maybe some type or damper. Then taking one vent thru the outside trailer wall. That way I can heat my annex room without heating the inside of trailer some much. Anybody done this? I’m having a hard time finding the venting and a air tight / water tight connection to go thru wall.
thx all
