Good indoor/outdoor 2 sensor thermometer for truck camper?

[Dave in AZ]

I read a ton of Amazon reviews... everything that starts out looking good, has 500 1star reviews warning they stop working in a week, or reads 20F wrong. Just want a cheap accurate thermometer to see temps inside and outside my truck camper! Thx

ThermoPro Dual Zone

I have used this unit for over 2 years with no issue.
Main unit runs on 2xAA batteries
Remote sensor is usb rechargable.

In two years only have had to change the batteries and recharge twice.

Where have you found the best place to mount the sensor for the outside temps?
