I assume this is not very common practice, but has anyone changed the color of their RV/trailer interior walls? The walls inside my 98' 5th wheeler are not very eye appealing and the decor is being changed soon. What kind of paint should a person use to change wall colors? I want something that will stick and not peel off after 2 years of use. I would also be interested in what kind of chemicals should be used to prep the walls for painting.
