I think your only out now that you have them in your coach is to use "Moth Balls". Put a hand full in a sock and place one sock in every compartment. That should drive them out, and maybe You also, so you will have to air out your unit...
I use moth balls year round, but only in the outside compartments. I hate the smell. Inside the coach i use dryer sheets in all the compartments. On a cool night in a c/g or camping in the woods they will enter. I've been using moth balls for years and have not had an issue with mice or other rodents.
