My 2016 Winnebago was also built on a Mercedes Benz Sprinter Chassis and it had the battery boost switch installed on it from Winnebago. The dealership service rep went out into their lot and looked at the Winnebagos built on the MB Chassis on their lot and everyone had the battery boost switch installed on them from Winnebago yet the THOR units built on the same MB Chassis did not. THOR decided not to include this feature.
