Hello everyone! my name is Jesse and im new to owning a pop up camper and yes! you ready that right. So heres the story. I bought a 97 coleman yukon used. very clean. I bought it to take this past weekend for a softball camping tournament. The first night we had it me and my cousin were sleeping on one side and our daughters on the other. in the middle of the night the king size side extension limit holder came off screws and extended out and surprised us with a sudden 2 inch fall. The girls thought it was funny. Later that same night, we had a tv i had setting over the sink and that fell over in the middle of the night also. But lets get to the reason why your here. on Thursday night, it was just me and my daughter in the camper this time. When i bought the camper, the guy told me the heater and ac didnt work. i thought nothing of it. I borrowed a portable ac unit from my friend and what must have happen that it was so cold in there the heater was trying over and over and over to kick on. We woke up to the smoke alarm and smoke in the camper. I looked and looked for were the smoke was coming and ended up seeing flames coming from outside the venting where the heater was at. i grabbed the extinguisher and put it out in time for no damage. but talk about your all time scare!!. We learned a valuable lesson in fire safety and taking caution. The rest of the weekend went fine. But what a way to start a pop up camper rookie experience!!!
