These are the 3 most important things to carry in your DIY campervan, rv, camper etc.
A smoke alarm, carbon monoxide detector and a fire extinguisher.
I decided to go ahead and install mine since we like plan on camping in the winter time
and we will be using a propane heat source.
The smoke detector and carbon monoxide detector together are less than $20.00 off Amazon.
I like the size of both of them and they should work nicely.
The smoke detector is a photoelectric smoke detector.
Steer away from Ion smoke detectors, they can take longer to
alarm and they aren't as sensitive as the photoelectric versions.
The carbon monoxide detector has a lcd screen on it, that will allow
you to actually have a reading of how many parts per million (ppm) you are being exposed to.
The LCD screen also changes to RED when dangerous levels of CO is detected.
As far as the installation of these safety items goes- follow the manufacturer's instructions.
