Just a fyi, if you live in a warm climate, and store your RV for extended periods, check the water in your toilet bowl, so it won't evaporate and make your seal dry out or any stink in ๐ just something I have always watched out for
I put Saran rap over the commode and close the drain plugs in the sinks. Cover the shower drain with a large flexible tub drain stopper. I do our stick and brick the same way when we leave the house.
