Hi Donald!

The MouseBlocker PROx Plug In Electronic Rodent Deterrent - 110V AC # MB34FR is rated to protect up to 400 square feet. However, it is mostly intended for direct protection and not necessarily a large area. Think vehicles, trailers, and even some Class A motorhomes (depending on their size). That kind of thing.

What are you thinking about using this for? Other than keeping pesky rodents away, of course.

Hey Donald, Did you decide where you're going to use the MouseBlocker PROx? I'm curious if it worked well for your vehicle or trailer, as it might help others in similar situations!

@MichaelI If you are asking if the MouseBlocker PROx Plug In Electronic Rodent Deterrent - 110V AC # MB34FR will work in a 30 foot RV, most likely. However, you are kind of on the cusp of being a bit too large so I would install two of them to be safe. One in the front and one in the back. This would give you overlapping coverage and little critters would be most displeased.
