Halloween & your trailer
It's a bit late to even think of this but, if your trailer can be easily moved to your driveway (front yard) and you've got access to some fairly strong strobe lights (brilliant white, red or whatever) think of the light show that could be going on inside the trailer as the kids coming trick or treating; as if the worst possible electrical storm imaginable is going on inside the trailer. Add sound if you’ve got access to such, i.e. thunder and some bloodcurdling screams. All this may be a bit much but the effects of what's going on inside your trailer would be the talk of the neighborhood, assuming some parent didn't report you causing you to enjoy Halloween at your local police station!
Perhaps a little over the top and not worthwhile doing but it's at least unique to think about.
