2023 Revel built on the Mercedes Sprinter 4x4 2500 chassis. 3.0 L, V6 diesel engine. Seven speed transmission. Pebble Grey. Service A completed 10/7/24. If you are not already familiar, google all of the unique features of the Winnebago Revel. I especially like the powerlift bed, the hydronic heating system, cabin AC, 320 Ah lithium ion battery, solar panel, 2000 W inverter, and a second dedicated alternator to charge the cabin battery. Perfect boondocking vehicle.
