Our 2001 Winnebago Adventurer had a 50 amp service as an option. Our 2013 Adventurer came with it as standard equipment. With the advent of residential refrigerators most middle of the road and higher end gas coaches have a minimum of 3-12 volt deep cycle batteries and a 2000 watt inverter/charger.
For 2015 (last year for full brochure available) the the Adventurer, Sightseer, and Vista lines of Winnebago motorhomes, and the Itasca Suncruiser, Sunova,and Sunstar lines have 50 amp services. They also have either 3 or 4-12 volt deep cycle batteries, and a 2000 watt inverter/charger.
