The featured Amazon option is Safe-T-Alert 20 Series Propane Alarm.
Where it fits my build
My Day 87 plan put the body openings ahead of the aluminum framing, flooring and wall panels. I specifically included the shower drain and the openings for three water tanks in that order of work.
I removed cargo tie-down hardware to leave mounting points for the extrusion framing, and removed door trim for the later insulation and paneling. SketchUp helped me plan how those separate jobs would fit together.

My build notes
The useful part of this diary entry is the sequence. I wanted to finish the drilling while the interior metal was bare, so later work would not mean opening finished surfaces again.
The photographs show my preceding floor-preparation session. Sweeping, washing and removing residue created the starting point for the interior work I described next.
I planned the openings and mounting access before enclosing the interior.
Alternative products
Two alternatives to compare
The 20 Series and 30-442 are propane alarms with different housings. The 35 Series alternative combines propane and carbon-monoxide detection in one housing, changing both the functions and the space occupied on a wall.
MTI 30-442 Propane Alarm
This MTI propane alarm connects to a 12V supply. Its white housing offers an alternative panel shape to the compact 20 Series unit.
