Respectfully sir, that is BP thinking.
1 - Propane is heavier than air so you can't smell it till the column of propane rises to your nose.
2 - Propane ignites at a mixture of approximately 2.15% to 9.5% propane to air.
3 - Propane simply burns outdoors, however in a confined space like a trailer, ignition of propane will cause a robust explosion rather than just a fire.
see: Propane Properties, Characteristics and Propane Gas Combustion Information
also see item 8: NJBA Page - NJBA, Propane Gas Forge Use and Safety
4 - The amount of propane that must build up in a trailer in order for a sitting or standing person to inhale and smell it is already enough to cause an explosion.
5 - There are lots of ignition sources in a trailer suitable to ignite a propane/air mixture (furnace piezo lighter, range piezo lighter, light switch, cell phone, etc.)
6 - Any person unfortunate enough to be inside or near a propane filled trailer that gets ignited is going to feel very bad about it, if they ever feel anything again.
for example, see: Suntrana, AK Propane Explosion, Sep 1964 | GenDisasters ... Genealogy in Tragedy, Disasters, Fires, Floods
and also: Propane Explosions Kill or Injure Thousands Each Year.
7 - Propane detectors are mandated by federal law for the reasons above.
If you still decide to remove your propane detector, please don't park anywhere near me or anyone else.
Do nothing all day; then afterwards, relax.
