Rv repair country coach

So today I worked on a country coach Rv it was built originally for the president of country coach back a while back the new owners take really good care of it but this Rv is amazing compared to most. The amount of things that go wrong with it are slim to none most the time. But today the inverter charger stopped working and we ended up replacing the coteoller after diagnosing that was the problem. Always fun getting to work on motorhomes and performing Rv repair.
