I've not felt a need to add a Security System to our trailer. Don't have one at our sticks and brick home either. We do have two dachshund sisters who never miss a trick. Nothing sneaks by them.
We do exercise caution and our basement doors stay locked. We lock the walk through door when we leave. Other than that, I'm happy to be able to report I feel most safe and secure RVing, and have felt no need for the expenditure of a Security System. I'd far rather spend my money on RVing goodies!
Did you get your trailer moved to the River Campground and have you been able to spend some time in it?
Owning one is just the ultimate in joy!!!
Glad you posted this thread. Keep on coming back, so we can get to know you bettern' better!!! :)
