If your motorhome already has one or two battery disconnect switches, you should verify that there is absolutely no draw of electricity from the batteries when the switches are in the “off” position. You wouldn’t think so, but some RV manufacturers design their systems so that even with the battery switch(es) turned off, there are still some devices that draw power, such as LP alarms or engine computer. This doesn’t have to be do-it-yourself work. RV dealers are used to dealing with these issues, and not a huge labor bill will be required to have it professionally done. The investment will save the aggravation of discharged batteries, and the expense of prematurely replacing batteries.
Note: Do not use the small battery disconnect switches that mount directly on the battery terminal, whether the knife-switch style or the type with the knob to tighten the connection. Both types tend to make poor connections after not a long time in use. The marine-style switches with a large selector dial are the best because they resist corrosion. If you do-it-yourself, be sure that you buy a switch with sufficient amp rating to match the batteries that you are connecting it to.
Fun Fact: Why do they call it “shore power”? Much of the technology and equipment for RVs came from the boating industry, and boaters called it shore power before RVing became popular, so the name stuck.
