Three bunk options. Two fixed bunks plus a power drop-down overhead bunk over the cab. Make the Aria 4000 one of the more versatile sleepers in the Class A diesel pusher segment, and the tilt-a-view King bed in back gives the master suite a genuinely premium feel. Two full baths mean no morning traffic jams, with the rear bath featuring a dual vanity, oversized fiberglass shower with skylight, and solid surface countertops. Under the hood, the Cummins ISB-XT 6.7L paired with an Allison MH-3000 transmission and air-ride suspension earns consistent praise from owners for a smooth, quiet highway experience that belies the rig's size. The cockpit is well-appointed too. Leatherette captain's chairs, a 14" touchscreen with Apple CarPlay and Android Auto, blind spot detection, and heated power mirrors with integrated side cameras all come standard.
