We too had a similar experience with running the heat for the first time. Alarms going off everywhere! To make matters worse, our youngest was sick, it was cold out but we had to vent the trailer.
All in all our trip to Hocking Hills, Ohio was cut short and our stay lasted just over 22 hours total. 3 hour trip there, arrive 9pm, tried a quick hike the next early afternoon but the little one was just too sick. Back to camp, packed up, out by 8pm headed home.
