Unfortunately speaking from experience, yes they do, and they can be just as destructive as mice. Found a nest they had built behind the access door to the generator oil filter. Had one area of a knitted throw blanket shredded and no evidence of mice in the coach. Replaced the blanket, they did it again. They can get in through the smallest of openings, and it is not always possible to close all possible points of access. I can deal with mice, just set traps and use Fresh Cab, but chipmunks are a different story. Used to think they were cute. Even had feeders in the back yard for the chipmunks and squirrels. Don't think they are so cute anymore.
