The seamless, easy-clean rotocast storage compartments have LED lighting for you to see at night and remote locking doors. A few other features you will appreciate include a water filtration system, multiplex wiring with a touch screen command center with Bluetooth phone app control, and an exterior shower in the service bay to keep the dirt outside where it belongs.
