Had a quick question about the best way to keep mice out of the RV for winter. We had issues last winter with them eating the window curtain on the front (need to completely replace that), nesting in the generator and making a mess out of the mattress for the bunk over the cab. We've managed to keep them at bay with bounce sheets over the summer but once we put the cover on and move the RV to the field behind the house we won't be able to access the RV after we get snow. DH found some spray online called Mouse Free http://www.mouse-free.com/store/do-it-yourself/ has anyone heard of this or used it? Is there another product anyone can recommend? Also, what do you do with the mattress in the master? We left it on last winter and surprisingly there were no mice issues with that but I don't want to take any chances. Thanks for any info you can provide.
