I have a 27 foot v-nosed enclosed trailer. I am running a 40,000 btu wall mount propane furnace that is mounted on the wall. It sticks out about 13 inches has 3 vents on the inside and vents directly to the exterior wall. The propane line runs down the inside of the wall along the bottom and to 2-30lb propane pigs on the front. It has a thermostat. This was the best money ever spent! Nothing neats coming back to the hotel at night cranking the thermostat full blast and let it go till morning. Sleds are totally dried off. It is essential to put a charging unit on the trailer hook-up so when the truck is running it charges the batteries in the trailer to run the furnace. If you want any emailed photos I would be glad to send them your way. I tried a norseman radiant in a smaller trailer years back and dont wast your money. If you want the chill off, buy a radiant heater. If you want a sauna, get a forced air furnace, be aware you will have everyone wanting to put there sled in your trailer,
