Good possibility of methane---------------
Add water to your "P" traps in your sinks to stop the flow of methane into the RV. After two months of storage, the water in the sinks "P" traps will evaporate making a path for methane gas to enter the RV. Methane is highly explosive and deadly to life. You should crack two windows in your RV for ventilation. One in the front area and one in the back. But make sure you pour water into the "P" traps.
