Wired probes have the advantage of being able to store them in liquid in the refrigerator. That eliminates temperature swings and reflects the status of the food in the refrigerator/freezer, not the air. That approach is a regulatory standard for monitoring refrigerator temperatures in a healthcare setting.
I don't have a monitor because I don't camp enough to justify it. We have a basic analog thermometer in each compartment. I'll also use the trick of putting ice cubes in a plastic bag in the freezer.
If I ever do feel compelled to spend more money on the trailer, I'll probably go the wireless route because I'm lazy, and because we can monitor it remotely while on the road.
