Very common for the OEM Thor house battery to fail fairly quickly after purchase due to dealer neglect.
Suggest that if your battery tray has enough space, best to have a minimum two house batteries.
You will always have a small draw from miscl 12 volt items (includes CO2 & smoke sensor)
Also, the solar panel mod is a great way to ensure that the battery bank remains topped-off.
