I will look at larger units, and the idea of using a heavy curtain/partition will go a long way I think.18,000 BTU Suburban heater for a 30'x 8' cargo trailer?Greetings, I haul steam engines around in a 3 axle 30'x8' cargo trailer. I think the walls have foam insulation, but they are thin. The walls are carpeted. The floor is 3/4" plywood right on the steel frame. Question: when we unload the steam engines we often camp in the trailer. We are doing our first cold weather trip... it could get down to freezing at the low. Do you think a 18,000 BTU Suburban heater would be able to heat that space? ***Link Removed*** Thanks,
