Had a 12 volt no power electrical issue in our coach. Their tech Gordon arrived on time, was pleasant and knowledgeable. Issue was diagnosed and repaired in little over an hour. Probably would've taken less time if I hadn't been peppering Gordon with questions about general RV maintenance and operation. I'm new to motorhome ownership and he was very helpful in answering my questions. Only negative of Happy Hals service is getting an appointment due to there busy schedule. Had to wait a week for the service call, but it was worth it.
