I hated the smoke detector in my 20 foot TT. The smallest amount of smoke would cooking would set it off. For sure Toast was a major culprit. Last year I found a newer one that was suppose to be less sensitive. It seemed to work and be what I needed. The weather has been bad this spring and I have only been camping once ( it sucks) . The other day while walking by the camper I heard the smoke detector going off. (There was obviously no smoke) I haven't had a chance to check it out yet, I just pulled the battery.
It was over 95f degrees in the camper that was setting in the metal shed that day.( Maybe over 100) Do these things go off when they get to hot ??????
