Sure, police have only done the CSI "The fiber analysis shows that perp had been wearing a baseball cap sold only as a promotional item at Target and there is pollen from an orchid that grows only in Bahamas, so let's cross check all the Target's customers from that time with the tickets to Bahamas, meanwhile I will call the judge for the warrant for our newspaper thief!" on TV, they probably only do this for high profile murders or $100K+ heists in real life so nobody is going to investigate who broke into your RV past asking any potential witness if available. Showing up to the crime in progress and stopping it is different. It used to happen quite regularly even in California.
