Out of sight out of mind is a good way as well...
If you lock up things the thieves just cut the locks and do more damage with cutting cables etc...
Got to park the trailer in the back somewhere and not out on the sidewalk so to speak...
I have been real lucky here at my house/neighborhood... Folks around here don't even lock their doors haha... I know we are doomed sooner or later...
My outside lights come on at night with motion sensors and we don't have dog's here - Just cats...
PROPANE TANKS and BATTERIES all go with Drug Factories etc... Sometimes you hear of the thieves taking the whole trailer to house their drug factories operations...
It just keeps getting worse and worse I guess with no end in sight... Doesn't matter where you live... Hate breeds more hate...
Having good Insurance is the best suggestion I reckon...
