I wish the smoke alarm companies would make an alarm for a small space such as a camper. The one that came with my 17' Casita
is exactly the same size and make as the ones in my house. And it was put at ear level. It is so ear splitting I wonder if I've lost hearing due to it.
It doesn't need to be that big and powerful in a small camper.
I will admit I took it out. We don't cook in the camper nor do we smoke.
