I replaced my own with a Kenwood in a Ford E-450. The hardest part is removing the dash trim to access the radio mount. All of the necessary wiring will already be in place, but you will have to replace the Axxera plug with the provided Kenwood plug. That involves matching wire colors and making good splices. It requires some patience and a minimum of skill. I've read that Best Buy is good with motorhome installations.
