Burglar Alarm Suggestions

I'd think about all you'd need in an RV, is a alarm that goes off when the door is opened. I'd not be worried about someone breaking a window to get in. They're going to come in the door. A door alarm would have to have a delay so YOU can enter. A fake system using a red flashing LED in the door window and a exterior keypad might be just about as good. When you get home always push a few buttons so anyone watching sees you. If I was to installed a siren, it would have to be located under the RV someplace so the dog didn't have to hear it going off. Personally, I have never worried about it anyplace we've camped. Where we stay in Maggie Valley, we leave it unlocked all the time but we know almost everyone there. I'd only worry if I was leaving it in a parking lot somewhere. Most RVer's seem to watch each others stuff. Everybody has to check out each others stuff. LOL!
