Believe me !!! First hand experience...my Lily is strictly a house cat...our first time taking her in our motor home was a nightmare...she freaked and tried to hide EVERYWHERE...under the slide out...tried to get in cupboards...howled incessantly...was able to find a very small cavity under the dashboard and managed to squeeze her way into the instruments panel...it was almost impossible to get her out...of course they don't come when called especially when they are terrified...I had one chance to grab her to keep her from going further in...I grabbed hold and yanked her out...I know I hurt her...not seriously...but we were far from home and could not have dismantled the dash...CHECK the entire RV...cover every single place she could possibly get into..do not let her outside and I have discovered she travels better when she is not confined to a cat carrier...she crawls under the comforter and disappears until we get to our destination then she is fine...happy camper...Good Luck and I repeat...cover every cubby hole!!!
