I noticed RV MFG's are not installing enough smoke detectors in their products. If the only smoke detector is placed in the kitchen/living area and a fire originates in a bedroom with the door closed???? . . . . In addition, smoke detectors placed on the ceiling should be placed on the wall instead. One dinky fire extinguisher in a new rv from the MFG. is not enough. I bought a larger multi-purpose for outside compartment and one near the bedroom, & purchased an additional smoke detector (for bedroom) and carbon monoxide also. CM - NV
