Question:

We have a 2009 Fleetwood Discovery diesel pusher and have had mice in there before. sometimes even squirrels and racoons! Would the Pro MB94FR be a good fit for the engine bay during winter storage?

Expert Reply:

Greg, the Pro MouseBlocker # MB94FR is an excellent choice for large Class A diesels. It wires right to your 12V battery bank, adds flashing LEDs for extra deterrence, and shuts off automatically if voltage drops below 11V. Since you’ve got a big rig, many owners install one Pro unit in the engine bay and a plug-in # MB34FR in the coach interior for full coverage.

Do you keep your Discovery plugged into shore power in storage, or just let the batteries sit? If you have power all the time, the extra plug-in model would be a nice add-on in addition to the Pro.
