1. You have NO warranty from Midwest. Midwest warranty is to first owner ONLY. You do have Mercedes warranty on the chassis if under the 3 years. The Mercedes warranty is 36/36. Powertrain goes to 100k. Your problem is a Midwest installed appliance problem
2. The genset has NO charger
3. The Inverter/Charger IS the charger and when 120 volts is supplied from the Genset, SHOULD charge the Coach batteries. If NOT and you do have 120 volts TO the Inverter/Charger(you need to verify this) then the charger section of the Inverter/Charger is bad and either fix or replace the Inverter/Charger. Usually cheaper to replace the Inverter/Charger. Doug(Midwest Dealer Technician)
