Is my car more likely to be broken into?

My car is clearly being lived in. I'm doing my best to keep valuables out of sight, but the passenger seat is out, the floor is a platform, and my mattress is rolled up in the back, along with a camping mat, pillows, window covers and shopping bags.

My logic is that a car that's being lived in is more likely than a regular car to contain stuff worth fencing.

Anyone have recommendations, or experience that can put my mind at ease?
