Hello fellow Nucamp owners. I am new to this whole rv world. I am wondering if mice getting into the Tab 400 is a common problem. My dealer is trying to sell me the Diamond Kote Mouse Shield undercoating which is supposed to seal any holes where mice can get in and also has a deterrent for mice built into the coating. Has anyone had this done? Has anyone had a mouse problem with a Tab 400? I’m wondering how well they are sealed underneath. Thanks!!
