X2. There is no "fix all", if there was don't you think we would have heard about it. Rodent damage is in the tens of millions across the board each year.
At night with slides closed (storage mode), flood the interior with light, crawl underneath and mark all light points. Steel wool and great stuff the openings.
For MH owners, make sure you put the air on recycle, that closes the door from the intake, which is another entry point. Also, if your lucky to have inside storage, keep the 5 gal pail trap outside your unit. Use. RV antifreeze in the bottom, they love to drink that stuff. Tastes soooo good!
