Windows

As newbies we were told to close all windows and vents or else the water in the sink traps would be sucked out and we would get bad smells in the rig. Forgot and left a max air covered roof vent open one time but no bad smells. Anyway, we still close everything.

For sure don't leave a back window down! Look at the back of the rig when you get somewhere. Don't want that inside. :(
