If they push back

Our reefer telematics already logs temperature.

OEM reefer logs rarely tie temp events to exact GPS stop and door context — K3 correlates for audits and claims.

Sensors are another thing to maintain.

BLE pairing is once per trailer; solar GPS sustains location even if a sensor battery is due — ~30 min install.

We only need this on pharma lanes.

Start on high-risk lanes; same hardware scales to food and retail without a second platform.
