Question:

We’ve got a 2020 Jayco Eagle travel trailer. Do I want the plug-in version MB34FR or the 12V Classic MB44FR for keeping mice out of the interior?

Kevin, if you’ve got access to shore power while your Jayco’s parked, the plug-in # MB34FR is the easy choice - just plug it into a standard outlet inside the camper, and you’re protected. If you store off-grid without power, the Classic # MB44FR can be wired to the trailer’s 12V battery system instead. Both use ultrasonic waves that bounce around the interior and keep mice from getting comfortable.

Do you normally have your camper plugged in when it’s in storage, or is it off the grid? This will help me recommend the best option for you.
