Question:
We’ve got a 2015 Keystone Montana fifth wheel. Would I need more than one MouseBlocker inside, or will a single plug-in MB34FR cover it?
asked by: Janice
Expert Reply:
Janice, a single # MB34FR plug-in covers about 400 sq. ft., which is enough for one section of your Montana. Because sound waves don’t pass through walls and cabinets, many RV owners install two units - one up front near the bedroom and another in the living/kitchen area - for full coverage.
If you’ve got basement storage, a Classic # MB44FR tied to the battery is a smart add-on too.
Do you want full-coach coverage or just the living area?
