Hi everyone, new to the Class A world

Always use only distilled water to keep the batteries to the ring. Mine are 19 years old and still good. They are Interstates. Then remember your coach has more outlets that draw power than power. That means you will have to reset circuit breakers if you overload the electrical system by drawing more than what is available. Also understand that HVAC systems require more AMPS to start up than they do after they get going. The generators need time to build up Amperage so wait a few minutes before turning on HVAC units, and turn one on then the other if you have more than one. Parks that you plug into power at also do not deliver Amperage at 30 or 50 just because they say that on outlet. The power is subject to the condition of the power on the line and at the plug in prongs and the circuit breakers both at the power plug in and throughout your RV, as the breakers oxidize and need replacement due to the spark and heat melting the metal. Ground wires on 12 volt systems are also constant problems due to weathering and road vibration loosening the contact points where the ground is connected. Also use the power that has the highest Amps for electric heaters which many use to conserve propane. Then the propane powered units are lite by 12 volt and are not going to lite if 12 volt system is not at 12 volt due to unrecharged battery. Then remember the generator will not run if you have less than a quarter tank of gasoline in the tank. That's to prevent you from running out of fuel for travel to the next fuel stop. So filling up before stopping for a long stay is smart. Then generators will not run if the oil pressure is not high, due to low oil level or leaking oil pressure sensor. Have fun in you new A.
