Being charged because service doesn't know what they're doing, we were charged $280 ,"diagnostics" to find a breaker switch on an inverter that they put in!! How do you charge that to flip a breaker and diagnose an inverter you put in,, that is absolutely insane and taking advantage of customers ,customers that have spent over 2 million dollars in Davenport for motorhomes. Never again. User's recommendation: Don't use their service department.
