A lot will depend on the size and capabilities of your current radio. If all it does is radio/CD then you will just need to determine the size, either a single/ one and a half, or double DIN. You might need some special tools to release the radio from the dash. The existing sleeve might be reusable. If the present unit is tied into other entertainment systems in the coach there will be other issues. The unit I just removed was also a NAV / with DVD and was tied into the Home Theater system. Crutchfield is a great source and they can give you a lot of info and choices.
