New Battery not holding charge in Toy Hauler with Generator

Help! We have a 2004 All American Toy Hauler 38CKDS (30 amp). We hooked it up to go camping recently and the battery was dead. It was out of warranty so went and bought a new one at Walmart. (Marine Ever Start 12 Volt). Worked fine to push the slides out when we got there. A week later when trying to pull the slides in the new battery was dead. Took it back to Walmart and confirmed dead. They gave us a new one, which got us home. However, we have disconnected it and are trying to figure out what is wrong. There appears to be 2 sets of wire running from the battery. One to generator (which we did not use) and 2nd to Converter/Inverter? (and where is it located?) The camper is hooked up full time to an outside 30 amp plug at home. We have also had some bad lightning storms which recently blew our home internet box. Any suggestions for trouble shooting this problem would be much appreciated!!

If you have voltmeter, disconnect shore power and measure voltage at battery and should be 12 volts or higher. Now connect shore power and measure battery voltage again, should 13 volts and higher. That's a start, it will tell you if battery is getting a charge or not.

Welcome to the forum!

There are parasitic losses such as the CO detector, clock on the radio, etc that will run down a fully charged battery in about a week. If the camper isn't plugged into shorepower you should disconnect the battery or install the battery disconnect switch to prevent it from being discharged.

As far as the wiring, one set of leads will supply the 12V fuse panel and 12V circuits in the camper. When the camper is plugged into shorepower, the camper's converter will convert 120V to 12V for the 12V circuits and charge the battery.

The second set of leads are probably from the generator to charge the battery if the generators running in absence of shorepower.
