Liquid Nails is your absolute best choice. The entire bottom of my Montana is sealed in with Liquid Nails. I've used Liquid Nails in 100% wet areas (after it dries), extreme heat, and extreme cold. It just doesn't fail. Beware though.... if you ever want to remove the mirror, you'll have to break it, then dig out the Liquid Nails, or just replace the wall the mirror was stuck too. Darn good stuff! That's why it's called Liquid "nails"!
(Plus! Liquid Nails never dries completely "hard." It always stays pliable. So, in an RV, the Liquid Nails will have some give for flexing, whereas your mirror and wall behind may not. Your mirror will do just fine!)
