Finally went camping after working on the camper and getting the propane line fixed which is great. However the sales guy did not explain how to use it and even after asking the repair guy didn't really explain how to do this. The result was my daughter and I were very cold despite having a little space heater. Can someone please explain this to me and give me step by step setup instructions? I checked the owners manual and it doesn't say and the furnace said instructions were inside but nothing was there (may have been there at one time but it is no longer there). I have a 1996 Laramie Coleman.
